Jakob Wennberg 9a56b7aff9 perf(bookkeeping): fiscal-year pickers and cash accounts read the session cache (#1934)
First consumer migration onto lib/reference-data. FyPicker and
FiscalYearSelector (14 consumer surfaces, 47 fiscal-period fetch sites
before this series) now read useFiscalPeriods(); with the layout seed the
restore of the persisted scope runs in the first effect tick and onReady
fires on mount instead of after a round trip. Their restore rules are
extracted into a pure resolveInitialFiscalScope() (lib/reference-data/
fiscal-scope.ts) so the two pickers cannot drift apart again, and the
restore runs once per company load, not on every background revalidation.

- /reports: the static catalog renders immediately; only the "no fiscal
  year" empty state waits for the picker (previously six skeleton bars
  until /api/bookkeeping/fiscal-periods resolved).
- JournalEntryList (/bookkeeping): resolves its initial scope from the
  cached list instead of its own fetch; the saved-scope shortcut still
  unblocks the entries fetch first when nothing is cached, and resolution
  is guarded to once per company so a revalidation can never snap a
  deep-link "all years" visit back to the stored year.
- /transactions: the account chooser reads useCashAccounts({ enabledOnly })
  (seeded) instead of fetching /api/cash-accounts on every visit; the bank
  sync button invalidates that entry after a sync.
- STORAGE_KEY_PREFIX / ALL_YEARS_VALUE move to a dependency-free
  fiscal-year-storage.ts (re-exported from FiscalYearSelector) so lib/ code
  can import them without a React component.

raw-reference-fetch ratchet: 55 -> 51 files.

Jakob Wennberg 47fe193c48 feat(perf): session-cached reference data layer, server-seeded, with a raw-fetch ratchet (#1932)
* feat(perf): session-cached reference data layer, server-seeded, with a raw-fetch ratchet

Customer report (2026-08-26): "it takes time before all fields load when
clicking around". The cause is on the client: fiscal periods, settings,
accounts, cash accounts, dimensions and templates are fetched raw from 47 /
27 / 14 / 8 / 12 / 5 independent call sites, uncached, on every mount and
every dialog open, each request paying the auth proxy and route wrapper
before its own query. SWR was adopted for exactly this on 2026-07-13 but
reached only three files.

This PR adds the layer; consumers migrate in the follow-ups.

- lib/reference-data/keys.ts: one key builder per data set, company id in
  position 1, null without a company; company_settings keeps the shape
  useCompanySettings already uses so that hook is seeded without a change.
- lib/reference-data/fetchers.ts: browser Supabase for fiscal periods and
  cash accounts (mirroring period.list and listForCompany ordering, pinned
  by tests), /api for the lists whose routes do real work (accounts RPC,
  dimensions ensure, template scoping, customer masking).
- lib/reference-data/hooks.ts: useFiscalPeriods, useCashAccounts,
  useAccounts, useDimensions, useBookingTemplates, useCustomers,
  useSuppliers, useArticles (+ re-exported useCompanySettings); one-minute
  dedupe, keepPreviousData, background revalidation kept on so writes from
  MCP/agents/other tabs surface.
- lib/reference-data/invalidate.ts: invalidateReferenceData(kind) for the
  success path of every client write.
- lib/reference-data/seed.ts + components/providers/ReferenceDataSeed.tsx:
  the dashboard layout fetches fiscal periods and cash accounts in its
  existing batch and hands them, with the settings row it already had, to
  SWR as fallback, so the first form of a session renders its period, bank
  account and settings-driven fields on first paint. getDashboardSettings
  now selects the full row for that (its other consumers read a subset).
  The chart of accounts is not seeded (hundreds of KB for large charts).
- scripts/checks/raw-reference-fetch.mjs, wired into check:guards as a
  per-file ratchet: GET-shaped fetch('/api/<reference path>') anywhere in
  client-facing code and .from('<reference table>').select( in 'use client'
  files. Baselined at 55 files; new sites fail CI; at 0 the entry goes.

* fix(checks): anchor every optional whitespace run in the raw-reference-fetch regex

CodeQL js/redos flagged the `\s*,?\s*\)` tail: two adjacent optional
whitespace runs around an optional comma backtrack polynomially on a long
near-miss. The URL and init-object pieces are now named fragments and
every whitespace run is followed by a literal, so there is one way to
match. Behaviour unchanged (same 7 fixtures + baseline count of 55);
a worst-case timing test pins the linear scan.

* fix(checks): make the use-client directive regex unambiguous (CodeQL js/redos)

An unclosed /* let the lazy comment body be re-split at every later /*.
The body is now (?:[^*]|\*(?!\/))* which cannot cross a */, so the outer
repetition has one parse. Pinned with a 3000-comment worst-case test.

* ci: re-trigger checks for the rebased head

No workflow ran for dd560a7af (nor after close/reopen); an empty commit
gives the pull_request event a fresh head. No code change.

* fix(checks): single-character whitespace alternative in the use-client detector (CodeQL js/redos)
