Closes the audit's HIGH §10 + MED §§17–22 isolation footguns. None of these are user-impactful TODAY — every site is preceded by a port- scoped read or pre-validated by ctx.portId — but each is a future- refactor accident waiting to happen, so the SQL itself now pins the tenant boundary: * mergeClients gains a callerPortId option; the route caller passes ctx.portId. removeInterestBerth now requires portId and verifies both the interest and the berth share it before deleting the junction row. All three callers updated. * Six service mutations now scope the WHERE to (id, portId): form-templates update + delete, invoices.detectOverdue per-row update, notifications.markRead, clients.deleteRelationship. company-memberships uses an inArray sub-select against port companies (no port_id column on the table itself), covering updateMembership / endMembership / setPrimary. * Port-scoped file lookups in portal.getDocumentDownloadUrl, reports.getDownloadUrl (file presign), berth-reservations.activate (contractFileId attach guard), and residential.getResidentialInterestById (residentialClient join). Test status: 1168/1168 vitest, tsc clean. Refs: docs/audit-comprehensive-2026-05-05.md HIGH §10 + MED §§17–22 (auditor-B3 Issues 1–5,7).
