Bug/open banking flow (#854)

* fix(enable-banking): pin Mobile BankID (decoupled) auth_method so Handelsbanken corporate connects

We never sent auth_method to Enable Banking, so it fell back to the ASPSP's
visible default — REDIRECT for Handelsbanken. For Handelsbanken *corporate*
PSUs the redirect flow does not support Mobile BankID, so authorization failed
right after the user approved in the BankID app. Mobile BankID at Handelsbanken
is a DECOUPLED method flagged hidden_method=true, which Enable Banking only uses
when requested explicitly.

Resolve the bank's preferred auth method before /auth: query the ASPSP's
auth_methods and pick the DECOUPLED (Mobile BankID) method when present,
otherwise leave auth_method unset so banks that already work are untouched.
The method name is read dynamically per psu_type, so it is robust across
sandbox/production naming.

- api-client: add approach/hidden_method to AuthMethod, fix ASPSP.auth_methods
  field name (was available_auth_methods, never populated), add
  getPreferredAuthMethod(), thread optional authMethod through startAuthorization
- index: resolve authMethod in /connect and pass it on both fresh + reconnect
- tests: cover method selection and request-body shaping

* refactor(invoice-inbox): clean up bulk-selection toolbar UI

Redesign the selection toolbar shown when inbox items are checked:
one solid primary "Bokför valda" button with outlined secondary
actions ("Fråga assistenten", "Ta bort") and a plain selection
count. Removes the redundant "Avmarkera" button (users uncheck the
still-visible box), fixes label clipping, and gives the toolbar more
breathing room.

* chore(entitlements): bypass paywall in local development

Add isPaywallBypassed() so all gated capabilities are testable locally
without a subscription. Fires only on NODE_ENV=development (npm run dev)
or an explicit DISABLE_PAYWALL=true escape hatch — production builds run
under NODE_ENV=production and the entitlement suite runs under 'test',
so both keep exercising the real gate.

* fix(tic): resolve enskild firma bolagsuppgifter via 12-digit personnummer

TIC's Lens search is fuzzy and only resolves an enskild firma from the 12-digit (century-prefixed) personnummer; a 10-digit form fuzzy-matched an unrelated entity. Expand personnummer to 12 digits before querying and reject hits whose registration number is unrelated to the request. Add a "Hämta" action to the settings Bolagsuppgifter panel to (re)fetch on demand.

* feat(transactions): implement categorize core for bank transaction categorization

- Added `categorize-core.ts` to handle categorization of bank transactions, supporting single and bulk operations.
- Introduced `categorizeMatchedTransaction` and `bulkBookMatchedInboxItems` functions for transaction processing.
- Implemented fiscal period validation and duplicate booking detection.
- Enhanced logging and error handling for transaction categorization.

feat(scripts): add diagnostic script for Handelsbanken ASPSP metadata

- Created `check-handelsbanken-aspsp.mjs` to fetch and display available authentication methods for Handelsbanken.
- Outputs metadata for business and personal PSU types, including default authentication methods.

fix(migrations): increase statement timeout for SIE bulk delete operations

- Updated `20260629160000_sie_bulk_delete_statement_timeout.sql` to set a longer statement timeout for bulk delete RPCs to prevent cancellations during large imports.

feat(migrations): add bulk book inbox items to pending operations

- Expanded `pending_operations` table to include `bulk_book_inbox_items` operation type in `20260630120000_pending_operations_add_bulk_book_inbox_items.sql`.
- Supports bulk booking of matched inbox items against bank transactions.

test(pg): add tests for replace_period_opening_balance_link RPC

- Implemented tests in `replace-period-opening-balance-link.pg.test.ts` to validate the functionality of the opening-balance correction flow.
- Ensured immutability of opening balance links and proper handling of posted vs. non-posted entries.

* fix(sie-export): update journal entries and lines handling in SIE export tests

* fix(migrations): resolve version collision on 20260629160000

The SIE bulk-delete statement_timeout migration shared version
20260629160000 with journal_entries_list_series_filter (merged from
main via #798/#823), causing a schema_migrations_pkey duplicate key
error on apply. Rename the branch's migration to 20260629160100.

* fix(compliance): resolve compliance-swarm + review findings

- opening-balance/correct: compensating rollback for the non-atomic
  storno+rebook so a mid-sequence failure never leaves two posted OB
  entries (ASVS V2.3); durable audit event on every failure path
  (V16); reference the original verifikationsnummer in the corrected
  entry per BFL 5 kap 5§; document that requireWrite already enforces
  write-role + membership (V8.2.1 was a false positive)
- reports sources routes: validate the cursor date component as ISO
  (/^\d{4}-\d{2}-\d{2}$/) before use, 400 on malformed (ASVS V1.2),
  applied to both the VAT-declaration and trial-balance routes
- AgentSessionList: await the rename PATCH, revert the optimistic
  title and toast on failure (ASVS V4.5)
- bank booking: exclude same-batch siblings from the booking-time
  duplicate guard so bulk-booking distinct same-(date,amount)
  transactions no longer false-positives; pre-existing duplicate
  detection is preserved
- BulkBookInboxDialog: drop the unsafe currency-based reverse_charge
  default, add an omvänd skattskyldighet advisory, and type VAT
  options to the backend VatTreatment union
- OpeningBalanceRowEditor: hold onChange in a ref (synced in effect,
  not during render) so an unstable callback can't cause a render loop

* Expand a 10-digit personnummer to the 12-digit (century-prefixed) form that
* Lens requires to resolve an enskild firma. Lens stores a sole trader under a
* 16-digit registration number derived from the 12-digit personnummer; the bare
* 10-digit form only ever fuzzy-matches, which is how a personnummer once
* resolved to an unrelated foundation.
*
* Detection is unambiguous: a Swedish organisationsnummer always has a 3rd digit
* >= 2, whereas a personnummer's 3rd+4th digits are the birth month (01-12). So
* a 10-digit number whose 3rd digit is 0/1 and whose month reads 01-12 is a
* personnummer and gets the century prefix; AB / förening / handelsbolag numbers
* pass through untouched. Century (19 vs 20) uses the same heuristic as
* `formatRedovisare`: a two-digit year greater than the current one is 1900s.

/**

* TIC v2 is a Typesense index and `query_by=registrationNumber` is a
* typo-tolerant full-text search: it returns ranked *near-misses*, not only
* exact hits. An identifier that isn't in the index therefore comes back as
* the closest lookalike number — a completely unrelated entity (this is how
* an enskild firma's personnummer once resolved to a random foundation).
*
* We validate the returned `registrationNumber` against the requested number
* before accepting a hit. The check is *containment*, not strict equality,
* because Lens stores an enskild firma under a 16-digit registration number
* that embeds the 10-digit personnummer (e.g. request `0201173275` →
* Lens `2002011732750001`). Requiring exact equality would wrongly reject
* every correctly-resolved sole trader. A genuine mismatch (Björn's case)
* has neither number containing the other, so it is still discarded and the
* caller sees a clean "not found" instead of a stranger's company.
*
* The upstream request is intentionally unchanged — the fuzzy `q=` call is
* what every working lookup already uses; we only tighten which hit we accept.
