Jakob Wennberg cc351158f8 Invoicing & account-security polish bundle (#550)
* feat: invoicing & account-security polish bundle

Five independent improvements bundled to ship together:

- BankID/password lockout fix: BankID-only users could enroll MFA and
  brick themselves (Supabase requires AAL2 to change password or unenroll
  MFA, and AAL2 needs a password sign-in). New app_metadata.has_password
  flag tracks this; middleware gates /mfa/enroll behind it, /account/set-
  password is the unlock path, SecuritySettings shows a banner, and
  /api/account/password is the single write path that flips the flag.
  Backfill script for existing users.

- Swish invoice payment method: company_settings.swish + invoice_show_swish
  columns, validation in lib/api/schemas.ts (accepts 123XXXXXXX företag or
  07XXXXXXXX mobile, strips whitespace/hyphens), rendered on invoice PDFs.

- Send-reminders kill switch: per-company company_settings.send_invoice_
  reminders toggle in PdfPrintSettings/Automatisering. Reminder processor
  also tightened: positive status allowlist (sent + overdue) so terminal
  statuses can never match; skip when customer already responded via
  reminder link; race-window re-check before send.

- First-invoice logo prompt: one-shot dialog when creating the first
  invoice without a logo (issue #520). Self-limits via head-only count.

- SIE export opening-balance fallback: route IB through getOpeningBalances
  so the compute_prior_opening_balances RPC supplies #IB after multi-year
  imports where opening_balance_entry_id is intentionally NULL. Previously
  #IB silently went to zero and #UB collapsed to current-period movements.

* fix(account-polish): address PR review feedback

- BankID-link path (extensions/general/tic/index.ts): read-merge-write
  app_metadata instead of passing { bankid_linked: true } alone.
  updateUserById REPLACES app_metadata wholesale, so the previous code
  would have wiped has_password for any user who later linked BankID,
  causing the set-password banner to (incorrectly) reappear and blocking
  the standard MFA enrollment button. The comment is now corrected.

- Middleware (lib/supabase/middleware.ts): thread inner returnTo through
  the /mfa/enroll → /account/set-password redirect so the user lands on
  their original destination after the full chain completes, not on /.

- safeReturnTo helper (lib/auth/safe-return-to.ts): replace the
  starts-with-/-but-not-// guard on mfa/enroll and set-password pages.
  The previous guard let /\evil.com and /@evil.com through. The new
  helper parses against a synthetic base origin and verifies it matches.

- set-password page (app/(auth)/account/set-password/page.tsx): remove
  CLAUDE.md design system violations — bg-gradient-to-b on page bg,
  inline shadow-md style on the card, space-y-5, font-medium on the h1,
  rounded-xl on the card. Flat surface, hairline border, font-display
  h1 per the design tokens.

- Swish dedup (lib/payments/swish.ts): extract normaliseSwish() and
  isValidSwish() helpers and use them in lib/api/schemas.ts,
  components/settings/BankDetailsForm.tsx, and the invoicing settings
  page. Single source of truth for the regex.

- Password route (app/api/account/password/route.ts): emit a structured
  success log so the audit pipeline can detect password-set events, not
  just failures.

/**
* Validate that a returnTo query param is a same-origin relative path.
*
* The previous guard only rejected protocol-relative URLs (`//evil.com`),
* but `/\evil.com`, `/?@evil.com`, and various other forms can still
* redirect off-origin in some browsers. Parse with a real URL and verify
* the origin matches.
*
* Returns the normalised path-with-search-and-hash on success, or the
* provided `fallback` if `value` is missing, malformed, or off-origin.
