fix(audit): reliability HIGHs — smart-restore re-link, TOCTOU lock, bulk wrong-interest, ext-EOI tx, bulk idempotency

R2-H1: smart-restore's berth_released auto-reversal was a no-op while
the wizard claimed success. Now uses the persisted interestId from
the decision detail to re-insert the interest_berths link and flip
the berth status back to under_offer. Verifies the interest still
exists and isn't archived before re-linking.

R2-H2: smart-archive berth status update had a TOCTOU race — read
outside tx, write inside without a lock. Now selects-for-update the
berths row inside the tx and re-checks status against the locked row
before flipping to available, preventing concurrent archive+sale
from un-selling a berth.

R2-H3: bulk-archive's berth→interest lookup fell back to
dossier.interests[0]?.interestId ?? '' which sent empty-string
interestIds that silently matched zero rows. Dossier now exposes
linkedInterestIds[] per berth (authoritative interest_berths join);
bulk + single-client wizard both use it and skip berths with no
linked interest. Affected:
- src/lib/services/client-archive-dossier.service.ts (DossierBerth)
- src/app/api/v1/clients/bulk/route.ts
- src/components/clients/smart-archive-dialog.tsx

R2-H4: external-EOI ran storage upload + 4 DB writes outside a
transaction. Now wraps file/document/event/interest writes in a
single tx; storage upload stays before the tx (S3 isn't
transactional), orphan-object on tx failure is acceptable.

R2-H5: bulk archive double-submit treated already-archived clients as
per-row failures. Bulk callback now early-returns success when the
dossier shows archivedAt is set, making the endpoint idempotent.

1175/1175 vitest passing.
