Fix/chrome pdf preview csp (#572)

* feat: add option to exclude year-end closing entries in SIE export and related reports

* delete docs

* fix: allow Chrome's PDF viewer in verifikat document preview

The /api/documents/:id/inline route shipped with
`object-src 'none'` in its CSP, which blocked Chrome's built-in PDF
viewer (it renders inline PDFs via an internal <embed>). Users on
Chrome saw "Det här innehållet har blockerats" when expanding a PDF
attachment in the bookkeeping view; Firefox (PDF.js) and Edge (own
viewer) were unaffected, and JPGs worked because <img> isn't subject
to object-src.

Drops the CSP for this route to the minimum needed for embeddability:
`frame-ancestors 'self'`. X-Content-Type-Options: nosniff plus the
fixed Content-Type from the handler already block MIME confusion;
X-Frame-Options: SAMEORIGIN + frame-ancestors still block clickjacking.

* feat(auth): add webmail deep link to email confirmation screens

Mirrors Stripe's signup UX: after asking the user to verify their email,
detect their webmail provider from the domain and show a button that
opens the inbox in a new tab. Gmail gets a from:<sender> search
pre-populated; Outlook/Yahoo/iCloud/Proton open the inbox directly.
Unknown / custom domains fall back to the existing copy.

Sender address is configurable via NEXT_PUBLIC_BRANDING_AUTH_EMAIL_FROM
(default noreply@gnubok.se) so white-label installs can match their
Supabase Auth SMTP config.

* fix(auth): unblock first-time password set for BankID users with MFA

Supabase rejects updateUser({password}) and mfa.unenroll with "AAL2 session
is required" whenever a TOTP factor is enrolled. BankID magic-link logins
produce AAL1, and middleware skips MFA enforcement for bankid_linked users,
so they had no path to AAL2 — leaving them unable to set a backup password
or disable MFA without going through the email-recovery escape hatch.

- /api/account/password: branch on app_metadata.has_password. First-time set
  writes via service.auth.admin.updateUserById (no existing credential to
  protect, AAL2 guard does not apply). Change-password keeps the user-session
  updateUser so AAL2 still fires for credential rotation.
- /mfa/verify: accept a safeReturnTo query param and route there after
  successful verify, so step-up flows can land back where they came from.
- SecuritySettings: detect the AAL2 error from both change-password and
  mfa.unenroll and redirect through /mfa/verify?returnTo=/settings/account
  instead of toasting a dead-end error.

* Add tests and rounding utility for öre precision in bokslut calculations

- Implemented `roundOre` function for rounding SEK amounts to two decimal places, ensuring consistent monetary calculations.
- Introduced `ORE_TOLERANCE` constant for comparing rounded amounts, facilitating invariant checks in financial entries.
- Created comprehensive tests for `roundOre`, covering typical cases, edge cases, and idempotency.
- Added year-end invariants tests to verify database-level guarantees for closing entries, ensuring they balance to the öre and reject discrepancies.
- Developed end-to-end tests for the dispositions chain, validating the correctness of calculations across various scenarios.

* fix: update PDF rendering to remove Swish QR code generation and set default to disable Swish visibility

* fix: enhance security by rejecting data URIs in safeReturnTo function tests

* fix: improve rounding logic in roundOre function and add customer_type migration

* fix: add customer_type column to customers and enforce CHECK constraint
