feat(bookkeeping): concept toolbar, template booking, confirm-first posting (UI migration PR 4) (#1123)

* feat(bookkeeping): concept toolbar, template booking, confirm-first posting (UI migration PR 4)

The Bokforing page adopts the concept (scene 9) on top of the PR 3 kit:

- Toolbar in concept order with the FyPicker chip far right replacing the
  "Visar:" scope selector (same persisted scope, one-click change)
- "Nytt verifikat" is a SplitButton with three remembered modes: Tomt
  verifikat (existing editor, voucher-number hint kept), Bokfor fran mall
  (new centered TemplateBookDialog: existing booking_template_library
  data MRU-ordered, date + editable amount recomputing the kontering
  live via applyTemplate, Balanserar row, direct booking + MRU touch),
  and Skapa med assistenten (existing agent-sheet path; suggestion lands
  in Granskning). Last-used mode persists via ui_state.create_mode
- Draft posting goes through ConfirmDialog describing the outcome
  ("Bokfors som verifikat A-218: ...") with an indicative next-voucher
  preview; the success toast still shows the real number
- "Underlag saknas" becomes the row's only warning chip (Badge warning)
  instead of the bare triangle icon; exempt rows keep the muted glyph
- New lib/hooks/use-ui-state.ts: client read of ui_state to seed the
  split button's initial mode

No backend, migration or RPC changes. VAT-split math is applyTemplate,
already unit-tested in lib/bookkeeping/__tests__/template-library.test.ts;
split-button persistence is tested in lib/ui-state.

* fix(bookkeeping): use roundOre in TemplateBookDialog money math

The antipattern ratchet caught two hand-rolled Math.round(x*100)/100;
route them through lib/money roundOre like the rest of the codebase.

* feat(bookkeeping): concept dry-table verifikat list (scene 9)

The list itself adopts the concept, verified against the artifact's
scene 9 markup: a borderless table (Verifikation / Datum / Beskrivning /
Belopp) with hover-revealed selection checkboxes, hover-revealed chevron,
and an animated grid-rows row expansion whose kontering renders as the
concept's vlines sub-table (uppercase hairline heads, Summa row).
Expansion actions become quiet underlined links (Visa detaljer, Skapa
andringsverifikation, Aterfor (storno), Kopiera); posting keeps its pill
+ ConfirmDialog. Drafts get a row-level Bokfor button like the concept.

All functionality preserved: batch "Inget underlag kravs" bar (above the
table), attachment counts + preview, no-doc-required toggle, out-of-
period + status badges, FX line amounts, sum footer, pagination. The
density toggle is dropped: the table has one density by design.

Fixes from verification: the list's i18n lives in the journal_list
namespace (new keys moved there; they rendered as raw keys otherwise),
and the sidebar brand Image gets explicit dimensions (Next dev warning).

* fix(bookkeeping): bulkbar appears only when a verifikat is selected

Concept behavior: no standing "Markera alla (62) / Markera alla utan
underlag" bar. The batch bar is hidden until the first row is selected
via its hover checkbox, then pops in with the count, the reason input,
Undanta underlagskrav, and quiet actions for Markera alla, the
filter-scoped bulk mark, and Avmarkera. All batch functionality kept,
just no chrome until it is needed.

 [2026-07-23] Frame layout (UI-migration PR 1) is md:-gated and the panel owns desktop scroll: mobile keeps document flow + bottom nav (concept is desktop-first), and since Next's window scroll-to-top never fires for an inner scroll container, MainContainer resets panel scroll on route change. Button default size drops fixed h-10 for natural pill height (7px/16px padding per locked convention 3); sm/lg/icon keep their heights.
 [2026-07-23] Nav PR 2: ui_state persisted as one jsonb bag on user_preferences (founder-approved migration 20260723120000) rather than per-preference columns: cosmetic, never load-bearing, grows with PR 3/4 split-button modes. Sidebar width driven by an inline --nav-w CSS variable on #dash-shell instead of a [data-nav-collapsed] attribute rule: the Tailwind 4/Lightning CSS pipeline silently dropped the top-level attribute-selector rule from compiled output, and the inline variable is pipeline-proof. Register/Bokslut folds default closed (concept tidiness), forced open by an active child route. Discord-community row skipped: no invite URL exists in the repo; add when one lands.
 [2026-07-23] PR 3 primitives: new --attn token pair (38 50% 34% light / 38 45% 62% dark) for the one-sentence AttnLine instead of reusing --warning: the warning tone fails WCAG AA as 12.5px body text on the page background; chips/charts keep --warning. Stagger applied via className on the five target pages' DataList/TableBody containers (plan item 7), not baked into the DataList primitive: remaining pages adopt it in their own migration PRs where their skeletons are aligned at the same time.
+[2026-07-23] PR 4 template booking books directly through the normal journal-entries endpoint without the editor's account-activation retry flow: template accounts are standard BAS accounts that are active in practice, and an inactive-account error surfaces as a normal error toast pointing at the full editor. Voucher preview in the commit ConfirmDialog is indicative (voucher-sequences/next for today's period/default series); the atomic number assigned at commit is what the success toast shows.
