feat(skattekonto): bulk Bokför + inline single-row booking (fewer clicks) (#1535)

* feat(skattekonto): bulk Bokför and inline single-row booking

Booking a year of skattekonto events took 6 clicks per row (list, Bokför,
review page, Bokför, confirm, navigate back), even for a +1 kr
intäktsränta row.

- GET /skattekonto/transaktioner now attaches a deterministic
  booking_suggestion per unbooked row (one hoisted skattekonto_rules +
  entity_type fetch via the new attachBookingSuggestions), shown as muted
  text on the inbox row ('Bokförs mot 8314 ...').
- New POST /skattekonto/transaktioner/bokfor-batch (Zod, max 200 ids):
  sequential draft+commit per row server-side (no orphan drafts), per-row
  results, never aborts on a row failure. Commit attribution: bulk_accept
  for real batches, user_accept for the one-row inline flow. A failed
  commit keeps the linked draft (degrades to the old review flow).
- Inbox: hover-reveal checkboxes on eligible SKV rows (suggestion
  present, no duplicate hint, unbooked, genomförd), separate skvSelectedIds
  set, bulkbar 'Bokför valda (N)' with ONE summary ConfirmationDialog
  grouped by suggestion with per-group sums, chunked batchProgress, ONE
  aggregate toast, local state patch with exit animation.
- Single-row: new SkattekontoBookDialog (dynamic import) replaces the
  draft-then-window.location detour on both /transactions and /skattekonto;
  'Öppna som utkast' keeps the old draft path via router.push.

* fix(skattekonto): batch booking guards for unsettled rows, double-post race and locked periods

- reject status != booked rows in the batch flow with NOT_SETTLED before
  any draft exists (server no longer trusts client eligibility); the
  single-row draft endpoint keeps its behaviour
- make the journal_entry_id backlink a conditional claim (update where
  journal_entry_id is null, select affected rows): zero affected rows maps
  to ALREADY_BOOKED and commitEntry only runs after a won claim, so two
  concurrent submissions can no longer double-post the same row
- detect the period-lock trigger signature in the batch catch and map it
  to PERIOD_LOCKED with Swedish text instead of UNKNOWN with raw DB output
- SkattekontoBookDialog: rows with no matched rule no longer get the
  guaranteed-422 draft CTA; they route to the existing match flow and to
  manual verifikat creation in /bookkeeping
- pass an explicit skv_book_dialog.commit_warning key for the
  direct-commit warning instead of ConfirmationDialog's hardcoded default
