feat(client-archive): smart-archive backend foundation (dossier + archive + restore)

The first slice of the smart-archive project. Replaces the dumb DELETE
client flow with a deliberate "look before you leap" pattern:

- New columns on clients: archived_by, archive_reason, archive_metadata
  (jsonb capturing every decision made during archive, so restore can
  attempt reversal). Migration 0043.
- client-archive-dossier.service builds a structured snapshot of "what's
  at stake" for a given client: pipeline interests, berths under offer
  (with next-in-line interests for the notification), yachts owned,
  active reservations, outstanding invoices, signed/in-flight Documenso
  envelopes, portal user, company memberships. Classifies the client as
  low-stakes or high-stakes based on pipeline stage (HIGH_STAKES_STAGES
  = deposit_10pct + later) so the bulk wizard knows which clients to
  prompt individually.
- client-archive.service.archiveClientWithDecisions takes the operator's
  decisions and applies them in a single transaction. Persists the
  decision log into archive_metadata for restore. Auto-handles portal
  user revocation + company membership end-dating; everything else is
  caller-driven. Surfaces external cleanups (Documenso void) for the
  caller to queue.
- client-restore.service.getRestoreDossier classifies each persisted
  decision as autoReversible / reversibleWithPrompt / locked based on
  the current state of the world (berth still available? new owner has
  active interests on the yacht? etc). restoreClientWithSelections
  applies reversals + un-archives the client.
- 4 API routes wire the services to HTTP. The existing /restore
  endpoint is upgraded to use the smart restore but stays
  backwards-compatible: clients archived before this feature have no
  archive_metadata so the dossier returns empty, and a POST with no
  body just un-archives them — same as before.

UI work + bulk variant + hard-delete + Documenso cleanup queueing land
in follow-on commits.
