feat(uat-batch): M43 follow-up — yacht detail field history

Extends Phase 3 from the M43 commit to yacht detail:
- New /api/v1/yachts/[id]/field-history endpoint joins through
  interests.yachtId (no schema migration needed) and filters to
  'yacht.%' paths so client-scoped overrides on the same interest
  don't bleed into the yacht surface.
- FieldHistoryScope.type accepts 'yacht'; provider URL routing
  generalised to /api/v1/<type>s/<id>/field-history.
- yacht-tabs OverviewTab wrapped in the provider; Name + the three
  ft-dimension rows get historyPath wired (m-dimension rows skipped —
  they're a unit-converted view of the same source value, and the
  supplemental writer only ever stores ft).

Addresses tab on Client detail intentionally left unwired — would
need AddressesEditor (a shared component) to surface icons per row,
which is more than the 5-min scope.

1454/1454 vitest, tsc clean.
