Matt Ciaccio e06fb9545b sec: lock down 5 cross-tenant IDORs uncovered in second-pass review ...

1. HIGH — /api/v1/admin/ports/[id] PATCH+GET let any port-admin
   (manage_settings) mutate any other tenant's port row by passing the
   foreign id in the path. Now non-super-admins must target their own
   ctx.portId; listPorts and createPort are super-admin only.

2. HIGH — Invoice create/update accepted arbitrary expenseIds and
   linked them into invoice_expenses with no port check; the GET
   response then re-emitted those foreign expense rows via the
   linkedExpenses join. assertExpensesInPort now validates each id
   belongs to the caller's portId before insert; getInvoiceById's
   join filters by expenses.portId as defense-in-depth.

3. HIGH — Document creation paths (createDocument, createFromWizard,
   createFromUpload) persisted user-supplied clientId/interestId/
   companyId/yachtId/reservationId without verifying those FKs were
   in-port. sendForSigning then loaded the foreign client/interest by
   id alone and pushed their PII into the Documenso payload. New
   assertSubjectFksInPort helper rejects out-of-port FKs at create
   time; sendForSigning's interest+client lookups now also filter by
   portId.

4. MEDIUM — calculateInterestScore read its redis cache before
   verifying portId, and the cache key was interestId-only — a
   foreign-port caller could observe a cached score breakdown.
   Cache key now includes portId, and the port-scope DB lookup runs
   before any cache.get.

5. MEDIUM — AI email-draft job results were retrievable by anyone who
   could guess the BullMQ jobId (default sequential integers). Job
   ids are now random UUIDs, requestEmailDraft validates interestId/
   clientId belong to ctx.portId before enqueueing, the worker's
   client lookup is port-scoped, and getEmailDraftResult requires
   the caller to match the original requester's userId+portId before
   returning the drafted subject/body.

The interest-scoring unit test that asserted "DB is bypassed on cache
hit" is updated to reflect the new (security-correct) ordering.
Two new regression test files cover the email-draft binding (5 tests).
