fix(interests): list yacht join + EOI status column + col redesign

Wire interests.yachtId -> yachts.name into the listInterests post-fetch
enrichment so the redesigned columns (Client · Yacht · Berth · Stage ·
EOI status · Source · Last activity) render the linked yacht.

- Add yachtId/yachtName to InterestRow.
- listInterests: fourth parallel join for yachts.name, Map merged
  alongside the existing client/berth/tag/notes joins.
- interest-columns: add Yacht column (with link to /yachts/[id] when
  the yacht has an id); replace Category with EOI status (badge
  driven by interests.eoi_status); drop default-view Tags.

The "Berth size desired" column called out in §5.2 is deferred to
Phase 2 since the underlying desired_*_ft columns don't exist yet.
