fix(reconciliation): Bankavstämning phase 0 — correctness + feedback batch (+ nav IA regrouping) (#879)

* feat(nav): interaction-mode sidebar grouping — Arbeta/Analys/Data/Skatt & bokslut

Nav IA redesign phase 0 (dev_docs/nav_ia_redesign.md): same routes,
regrouped by what the user is doing. CLAUDE.md restructured around Hard
Rules (doc references updated); pending-page explainer removed.

* fix(reconciliation): correctness + feedback batch for Bankavstämning (phase 0)

Engine: fetchAllRows pagination on status/run/RPC fetches (silent 1000-row
cap corrupted totals), optimistic-lock guards on manualLink + apply,
unlink audit rows attributed to the acting user (was: company UUID),
selected_matches partial apply intersected with a fresh match run.

View: silent in-place refresh instead of a full-page skeleton per action,
checkbox-gated apply with confidence badges (fuzzy unticked) in chunks of
500, honest result toasts, dry-run errors surfaced, ranked per-row picker
candidates pinned to the applied date window, currency-correct amounts
(bank side in account currency, GL side SEK), voucher links, translated
source types, colored differens, dirty-date-filter guard.

Discovery: year-end preflight 404 href fixed (/reconciliation/bank never
existed), ⌘K palette entry, real links from the transactions page.

v1: status registry schema now matches the actual ReconciliationStatus
payload, errors documented as a count, false ~0.85-threshold pitfall
replaced, route test mocks the real shape.
