fix: surface active TIC companies + block duplicate org numbers (#344)

* fix: surface active TIC companies + block duplicate org numbers

Three fixes from live-prod testing:

1. Enrichment filter hid the user's directorships. Now accepts both
   Completed and PartiallyCompleted status from TIC (tenants without
   CompanyRoles enabled still get SPAR) and the /select-company role
   filter no longer requires companyStatus === 'Aktivt' — real TIC
   payloads have been observed with different values, and positionEnd
   alone is the authoritative "currently a director" signal. Added
   PII-free diagnostic logs so the next shape-mismatch is debuggable
   from Vercel logs without a round trip.

2. Manual wizard silently allowed duplicate org numbers. Added:
   - findExistingCompanyByOrgNumber helper in actions.ts (service role,
     bypasses RLS to see cross-tenant rows)
   - Server-side guard in createCompanyFromOnboarding — returns
     'org_number_exists' before the create RPC so we don't leave ghost
     companies
   - New /api/company/check-org-number endpoint for debounced client
     checks
   - Warning + disabled submit in Step2CompanyDetails
   - Friendly error toasts in WelcomeOnboarding + BankIdCompanyPicker
   - Mirror cleaned org_number onto companies.org_number on creation so
     future duplicate checks and lookups are reliable

3. /onboarding ignored ?org_number= when the picker routed there as a
   fallback. Now reads searchParams and pre-fills settings; also fixed
   a latent bug where Step1's entity-type change wiped the pre-fill on
   *first* selection (it should only reset on a genuine change).

Tests: duplicate-org guard (with formatted-input normalization),
check-org-number route (auth + 400 + exists true/false +
normalization).

* fix: address PR review feedback on duplicate-org guard

Greptile P1 findings + swedish-compliance feedback:

- findExistingCompanyByOrgNumber now throws on Supabase error instead
  of silently returning null. Previously a DB outage or RLS
  misconfiguration would bypass the entire duplicate guard and allow
  duplicates through.
- createCompanyFromOnboarding catches the throw and returns a
  user-facing error ("Kunde inte verifiera organisationsnummer"),
  failing closed instead of open.
- companies.update({ org_number }) error is now checked and triggers a
  rollback. Silent failure would leave the company without an
  org_number, breaking all future duplicate checks for that entity.
- New normalizeOrgNumber helper validates 10- or 12-digit input,
  strips the century prefix for 12-digit personnummer form, and
  rejects anything else. Malformed input would have corrupted SIE4
  (#ORGNR) and SRU (INFO.SRU) exports downstream.
- /select-company now uses loose `== null` for positionEnd — TIC has
  been observed returning `undefined` for open-ended positions, which
  strict `=== null` would silently filter out. Documented the two
  downstream isCeased guards so future maintainers don't remove one
  without the other.
- createCompanyFromTicRole refuses to provision when lookup.isCeased
  (BFL 2 kap — bokföringsskyldighet ends at avregistrering).
  BankIdCompanyPicker surfaces this client-side too.
- WelcomeOnboarding + BankIdCompanyPicker recognise new error codes:
  org_number_invalid, company_ceased.

Tests: +4 cases covering malformed input rejection, fail-closed
behaviour on DB error, 12-digit personnummer normalization, and the
ceased-company refusal path. Full suite: 2306 passing.

Out of scope for this PR (follow-up):
- Partial unique index on companies(org_number) WHERE archived_at IS
  NULL. Closes the race-condition window but needs a migration plus
  any existing-duplicate cleanup — too risky for this hotfix.
- Rate limiting on /api/company/check-org-number. Endpoint is
  auth-gated so not an immediate concern.

* fix: add Luhn validation and extract org-number normalization

Third round of PR review feedback (swedish-compliance):

- Add Luhn-10 check-digit validation to normalizeOrgNumber. Rejects
  structurally invalid org_numbers (wrong check digit) at the boundary
  instead of letting them propagate into SIE4 #ORGNR and SRU INFO.SRU,
  where Skatteverket and receiving accounting systems would reject
  them later anyway. Reuses the existing luhnValidate helper from
  lib/bankgiro/luhn.ts (Bankgirot 10-modulen — same algorithm applies
  to both Bolagsverket org numbers and Swedish personnummer).

- Extract normalizeOrgNumber into lib/company-lookup/normalize-org-number.ts
  so the server action and /api/company/check-org-number use the same
  rule. Previously the API route only stripped hyphens/spaces, so a
  12-digit input would miss a stored 10-digit duplicate and mislead the
  client debounce check ("not a duplicate" → submit → server rejects).

- /api/company/check-org-number now returns exists=false for
  Luhn-invalid input rather than querying the DB. The submit-time
  server action surfaces org_number_invalid, which is the right place
  for the error.

Test coverage: dedicated normalize-org-number.test.ts (10 cases
covering both-lengths, Luhn, whitespace tolerance, garbage). Updated
existing tests to use Luhn-valid numbers (real Volvo 5560125790,
synthetic personnummer 8001011231). New failing-Luhn test in
actions.test.ts. New 12-digit-normalization and
luhn-invalid-returns-false tests in route.test.ts.

Full suite: 2315 passing.

Not fixed (out of scope for this hotfix):
- 10↔12 digit round-trip fragility for personnummer born 2000+. This
  is a codebase-wide architectural choice (see lib/skatteverket/format.ts
  which uses a two-digit-year heuristic to choose 19/20 at export).
  Migrating to 12-digit storage is a separate refactor.
- Server-side re-fetch of TIC /lookup for isCeased. The trust boundary
  here is user-to-their-own-onboarding, not adversarial; doubling TIC
  API cost isn't proportionate.
