feat(settings): API & MCP tab: correct connector URL namespace, plugin path, Swedish guide (#2105)

* feat(settings): API & MCP tab: correct connector URL namespace, plugin path, Swedish guide

The in-product MCP URLs omitted `tool_namespace=accounted`, and
resolveMcpToolNamespace() falls back to the legacy `gnubok_` prefix when the
param is absent. Every connection made from Settings therefore got `gnubok_*`
tool names while the docs, the accounted-api skill, and
claude-plugin/.mcp.json all reference `accounted_*`.

- Add `tool_namespace=accounted` to the Claude.ai, Claude Code, and
  Claude Desktop snippets.
- Move the Claude Desktop bridge from `npx gnubok-mcp` / `GNUBOK_API_KEY` to
  `npx -y accounted-mcp` / `ACCOUNTED_API_KEY`, and emit `ACCOUNTED_URL` so
  self-hosted and white-label instances get a config pointing at their own
  host. The `gnubok_sk_` key prefix is unchanged: it is wire format.
- Surface the Claude Code plugin, the only path that configures the
  connection and the seven workflow commands in one step.
- Rename the settings tab "API" to "API & MCP" and rewrite its intro: the
  MCP connection is what most users come here for, not API keys.
- Link the step-by-step guide from the panel, locale-aware.

Docs: add a Swedish /docs/api/anslut-claude alongside the English page (the
docs site has no locale routing, so each language is its own URL), give both
the Claude Code plugin path, and teach the export and freshness scripts about
the new page so cross-repo drift is caught.

* fix(settings,docs): Cursor is not Claude Code; use the accounted_ tool name

Review follow-up on #2105.

`claude mcp add` is a Claude Code command. Cursor does not read it, so the
"Claude Code / Cursor" row and the docs sentence pointing Cursor users at that
command were both wrong (the row predates this PR; the docs sentence did not).
Cursor now gets its own row and its own `~/.cursor/mcp.json` snippet with the
`url` field, in the panel and in both docs pages.

Also `vat_close_check` -> `accounted_vat_close_check` in the reviewer test on
both pages, matching the identifier used in the prompts section above it.

* feat(settings,docs): one-click Connect to Claude, and cut the panel to one action

Anthropic documents an install link for custom connectors:
https://claude.ai/customize/connectors?modal=add-custom-connector&connectorName=NAME&connectorUrl=ENCODED
(claude.com/docs/connectors/building/directory-vs-custom). It opens claude.ai
with the connector name and URL prefilled; the user still reviews and confirms,
and it grants nothing on its own. We were telling people to copy a URL and go
paste it somewhere else instead.

Settings panel, rendered and reviewed:
- "Connect to Claude" button is now the only thing above the fold. Everything
  that needs a config file or a terminal (claude.ai manual paste, Claude Code,
  the plugin, Cursor) moved into one "Other clients" disclosure, and the
  API-key methods keep theirs. Four code blocks -> one button, 1057px -> 719px.
- The connect group renders above the API-keys group. Connecting is why users
  open this tab; the tab's own intro says so.
- Each entry inside the disclosures shows its instruction as visible text.
  They were `?` HelpPopovers, so the panel read as opaque code blobs with no
  instructions on screen.
- Prose interpolates the brand's real casing, not the lowercased config key.

Docs, both languages: Path A leads with the install link and drops from five
manual steps to a link plus three short paragraphs, with the manual paste kept
under a subheading. No raw HTML: the docs renderer has no rehype-raw, so
<details> would have been silently dropped.

* fix(settings,docs): correct claude mcp add syntax and the SSR install link

Review follow-up. Both findings verified before acting on them.

`claude mcp add --help` gives `claude mcp add [options] <name> <commandOrUrl>`:
the URL is positional and there is no `--url` flag, so the API-key snippet
would have failed on a missing argument. Both commands now put
`--transport http` before the name and pass the URL positionally, in the panel
and in both docs pages.

The panel is server-rendered before it hydrates and window.location has no
server equivalent, so the install link was built from a relative mcpBase in the
first paint. A click in that window would hand claude.ai a connectorUrl it
cannot resolve. The origin now resolves after mount and the anchor carries no
href until it is known, which also makes it unclickable rather than wrong.
Verified: the SSR HTML contains no claude.ai href and no relative connectorUrl,
post-hydration the href is absolute, and there are no hydration warnings.

DECISIONS.md: code-span the `gnubok_*`/`accounted_*` wildcards so they stop
rendering as emphasis, and drop the "no one-click deeplink" claim from the
earlier entry rather than leave a false statement standing two lines above its
own correction.

 [2026-09-01] multi_user skeptic fixes: Stripe cancel EXPIRES the multi_user stripe grant instead of deleting it (grace anchor; other grants still deleted per freeze-and-retain); app-side state checks go RPC-first via SECURITY DEFINER company_multi_user_state (capability_grants RLS hides team rows from non-team users, byrå clients would misread as frozen); byra-kind teams get a standing team-scoped multi_user grant via backfill + teams trigger (WL-10 assumption made real; partner billing is out-of-band); PGRST202 on resolution fails OPEN (pre-migration DB has no multi_user rows: gated fallback would freeze all non-owners); /api/v1 got the same dormancy gate as MCP. RLS-level enforcement and the mid-session API fallback write-back window stay v2 follow-ups (documented, same class as pre-existing stale-preference fallback).
 [2026-09-01] Declined CodeRabbit's UpgradeNote suggestion (PR #1758 follow-up) to append the self-host connector sentence to children instead of replacing them: every caller's children is hosted subscription copy ("... kräver ett abonnemang"), so appending would show subscription wording on a self-host, the exact thing the branch exists to avoid; the "CSV/SIE import stays free" text it cited is a code comment in BankSyncNowButton, not children. Replace-on-self-host stays; a dedicated selfHosted children prop can come when a caller actually needs per-panel reassurance there.
 [2026-09-01] getConnectorConfig() rebuilds baseUrl as origin + path (userinfo/query/fragment stripped, warn-logged without the raw value): /api/connector/status echoes baseUrl to the operator and the sync/proxy URLs get paths appended, so nothing secret-shaped pasted into GNUBOK_CONNECT_URL may survive; the stripped parts were never meaningful in a base URL. The status route is also Cache-Control: no-store (key prefix + wiring layout out of shared browser caches).
+[2026-09-01] Settings -> API renamed "API & MCP" and its MCP URLs now carry tool_namespace=accounted: resolveMcpToolNamespace() falls back to the legacy gnubok_ prefix when the param is absent, so every connection made from the in-product surface got `gnubok_*` tool names while the docs, the accounted-api skill, and claude-plugin/.mcp.json all reference `accounted_*`. The Claude Desktop block also moves from npx gnubok-mcp/GNUBOK_API_KEY to npx -y accounted-mcp/ACCOUNTED_API_KEY and emits ACCOUNTED_URL so self-hosted and white-label instances get a config pointing at their own host instead of app.accounted.se. The gnubok_sk_ key prefix itself is unchanged (wire format, per CLAUDE.md).
+[2026-09-01] Connect-with-Claude ships in two languages as two URLs (/docs/api/connect-claude, /docs/api/anslut-claude) rather than adding locale routing to the docs site: the docs site has no i18n layer, the audience for the Swedish page is end users rather than integrators, and two hand-synced pages is a smaller standing cost than a locale system nobody else needs. Both are exported by scripts/export-docs-to-website.mts and both are asserted by scripts/check-docs-freshness.mts, so drift between repos is caught by the docs loop.
+[2026-09-01] Corrects the 2026-07-27 line further down "Claude Code plugin homepage points at the GitHub README": the connect-claude page WAS ported to gnubok-website and docs.gnubok.se/connect-claude has returned 200 since. The plugin homepage can point at the docs page whenever it is next touched; no separate change opened for it.
+[2026-09-01] Claude Code plugin install (/plugin marketplace add erp-mafia/accounted) surfaced in-product and in the docs. It is the only path that configures the connection AND the seven workflow commands in one step, and the marketplace manifest is public (verified: raw.githubusercontent 200, repo visibility PUBLIC). Directory listing (an Anthropic review that gets the connector a native Connect button and in-product discovery) is a separate founder task and still open; the one-click install link for custom connectors is unrelated to it and is covered below.
+[2026-09-01] Settings -> API & MCP leads with a one-click "Connect to Claude" install link (https://claude.ai/customize/connectors?modal=add-custom-connector&connectorName=&connectorUrl=, Anthropic's documented format) instead of four equal-weight copy-blocks. Earlier in the same session I asserted no such deeplink existed; that was wrong, it is documented at claude.com/docs/connectors/building/directory-vs-custom. The link only prefills the dialog (user still reviews and confirms) and requires the instance to be reachable from Anthropic's cloud, so the manual URL stays as a fallback for localhost and firewalled self-hosts. Everything that needs a config file or a terminal (Claude Code, plugin, Cursor, Claude Desktop, API keys) moved behind two disclosures: the default panel went from four code blocks to one button, 1057px to 719px.
+[2026-09-01] The connect-MCP group now renders above the API-keys group on /settings/api, and each entry inside the disclosures shows its instruction as visible text rather than a HelpPopover. Connecting a client is why users open the tab (the tab intro says so); key management is the secondary job, and four stacked `?` popovers meant the panel read as opaque code blobs with no instructions on screen.
 [2026-09-01] EB callback cross-company guard: an account the connection row itself already carried keeps its own enabled state even when a sibling company claims the IBAN (own-prior outranks claim): flipping a standing feed off on renewal would break legacy pre-session-sharing overlaps, while the F1 exposure only involves accounts NEW to the row. Claim-lookup failure fails closed to enabled:false but still mirrors (unknown claim state is not a proven foreign claim; skipping the mirror on a transient error would strand normal single-company connects).
 [2026-09-01] Provider-migration kreditfakturor import as ordinary invoice rows with reversed amounts and status 'credited', always unlinked. No provider DTO carries a reference to the credited invoice, so exact-match linking has no input to match on; guessing would corrupt the AR ledger. The wizard now says so rather than burying them in `skipped`.
 [2026-09-01] OAuth callback replay is fixed with no-store plus history replacement only, with no "Anslutningen ar redan klar" page. Keeps the anti-oracle property that consumed-vs-unknown state stays unobservable to an unauthenticated caller.
