The same `interface AuditMeta { userId; portId; ipAddress; userAgent }`
was duplicated in 26 service files. Move the canonical definition into
`@/lib/audit` next to the related types and update every service to
import it. `ServiceAuditMeta` (the alias used in invoices.ts and
expenses.ts) collapses into the same name.
Tag CRUD across clients/companies/yachts/interests/berths followed an
identical wipe-then-rewrite recipe with two latent issues: the delete
and insert weren't wrapped in a transaction (a partial failure left
the entity with zero tags) and the audit-log payload shape diverged
(`newValue: { tagIds }` for clients/yachts/companies but
`metadata: { type: 'tags_updated', tagIds }` for interests/berths).
Extract `setEntityTags` in `entity-tags.helper.ts` that performs the
delete+insert inside a single transaction, normalizes the audit payload
to `newValue: { tagIds }`, and dispatches the per-entity socket event
through a switch so `ServerToClientEvents` typing stays intact.
The five `setXTags(...)` service functions now do parent-row tenant
verification and delegate the join-table work + side effects.
