fix(connect): PR #1758 CodeRabbit follow-up: connector status hardening, i18n strings, doc alignment (#2098)

* fix(connect): PR #1758 CodeRabbit follow-up: harden connector status, i18n the connector-mode strings, align docs

- getConnectorConfig() rebuilds baseUrl as origin + path: userinfo, query
  and fragment are stripped (warn-logged without the raw value) so nothing
  secret-shaped pasted into GNUBOK_CONNECT_URL survives into the
  /api/connector/status echo or the derived proxy URLs (CWE-200)
- /api/connector/status responds Cache-Control: no-store on both branches
  (key prefix + wiring layout out of shared browser caches, CWE-525)
- CWE-319 thread verified as no-change: both connector-mode helpers derive
  from getConnectorConfig(), which fails closed on non-https
- SkatteverketConnectPanel tooltips and BankSyncNowButton gate/upsell
  strings moved to messages/sv.json + messages/en.json keys
- DECISIONS.md: MD037 fix on line 1146 (backtick the glob), line 1147
  reworded to grants-written-wiring-pending, decision lines appended
  (incl. declining the UpgradeNote children-append suggestion)
- docs/SOVEREIGN.md availability wording aligned with SELF-HOSTING.md:
  infra merged, keys issued manually on request, client wiring pending

* docs(connect): skeptic follow-up: bank client wiring is merged (#2094), SKV pending, no keys issued until it lands

Skeptic refutation on PR #2098: SOVEREIGN.md claimed the services 'do not
carry traffic' while this branch already contains #2094 (EB client proxy
routing), and 'issued manually on request' contradicted the standing
no-key-before-full-PR6b rule while skatteverketConnectorMode() has no
client consumer yet. SOVEREIGN.md, SELF-HOSTING.md and DECISIONS.md line
1147 now all say: bank client wiring merged and carries traffic with a
key, Skatteverket client wiring ships in a following release, keys are
not issued until it lands.
