test(audit-fixes): cover the new permission and webhook surfaces

Adds integration coverage for the routes / handlers shipped in the
preceding audit-fix commits, plus refactors two route files to expose
inner handlers from a sibling `handlers.ts` (the pattern used elsewhere
in `src/app/api/v1`) so tests can call them without the
`withAuth(withPermission(…))` wrapper.

New tests (18 cases across 4 files):
- `tests/integration/portal-auth.test.ts` (6) — verifyPortalToken
  rejects tokens missing `aud: 'portal'` or `iss: 'pn-crm'`, with the
  wrong audience (CRM-session-replay shape) or wrong issuer, plus a
  round-trip happy path. Locks in the portal-vs-CRM token isolation.
- `tests/integration/api/saved-views-ownership.test.ts` (6) — patch
  and delete handlers return 403 for a different user, 404 for an
  unknown id or cross-port id, and 200 for the owner. Ownership is
  enforced at the route layer regardless of the service's internal
  filtering.
- `tests/integration/api/berth-reservations-list.test.ts` (3) — the
  new global list returns rows for the current port only and honors
  pagination params. A reservation in a different port never leaks.
- `tests/integration/documents-expired-webhook.test.ts` (3) —
  handleDocumentExpired flips the document to `expired`, also flips
  the linked interest's `eoiStatus`, writes a `documentEvents` row,
  and is a no-op (not a throw) when the documensoId is unknown.

Refactors:
- `src/app/api/v1/saved-views/[id]/route.ts` extracts `patchHandler` /
  `deleteHandler` (and the shared `assertViewOwner`) into
  `handlers.ts`. The route file is now a 4-line `withAuth(handler)`
  wrapper.
- `src/app/api/v1/berth-reservations/route.ts` extracts `listHandler`
  similarly. Tests import directly from `handlers.ts`.
