chore: post-bankid redirect, recapt feedback, TIC SPAR enrichment (#400)

* chore: post-bankid redirect, recapt feedback, TIC SPAR enrichment

- BankID login + register now redirect to /select-company so the picker
  shows freshly enriched CompanyRoles from the current session.
- New lib/support/submit-feedback util prefers window.recapt feedback
  widget when present, falls back to /api/support/contact. SupportLink
  uses it and hides itself in sandbox companies via new isSandbox flag
  on CompanyContext (+ useCompanyOptional hook).
- TIC enrichment re-requests SPAR alongside CompanyRoles now that both
  types are enabled on the tenant; enrichment shape logged PII-free
  (booleans/counts only). Tests cover the SPAR+CompanyRoles path.
- Skatteverket api-client: 15s AbortSignal timeout on outbound requests.
- Swedish compliance review CI: bump REVIEW_MODEL to claude-opus-4-7.

* fix(tic): don't persist SPAR PII to extension_data

The previous commit started requesting SPAR alongside CompanyRoles and
wrote the full enrichment payload (incl. personnummer, full name, home
address, birth date, gender) verbatim to extension_data.value — a plain
JSON column. Personnummer is already hashed + encrypted in
bankid_identities, so the extension_data row was an unencrypted PII
duplicate exposed to anyone with read access to the table.

No consumer (middleware, /select-company, createCompanyFromTicRole)
reads any SPAR field today; they only read companyRoles. Persist a
sanitized blob of { companyRoles, enrichedAtUtc } instead. SPAR is
still requested from TIC (and its shape logged PII-free) so enrichment
completes; if address pre-fill ships later, those fields should be
encrypted before storage.

Also drop the dead `null` branch from SubmitFeedbackResult.channel —
every code path returns 'recapt' or 'email'.
