- ClientData in client-detail.tsx now reflects the stripped shape from
Task 8.2 (drop companyName/isProxy/proxy*/yacht*/berthSizeDesired) and
gains yachts / companies / activeReservations arrays.
- client-tabs.tsx: Overview trimmed (personal, contacts, source, tags);
three new count-badged tabs (Yachts, Companies, Reservations).
- New client-yachts-tab.tsx renders owned yachts + Add yacht CTA (TODO:
YachtForm preset-owner wiring for v2).
- New client-companies-tab.tsx renders memberships with Primary badge and
since-date; management still lives on the company detail page.
- New client-reservations-tab.tsx maps activeReservations into ReservationRow
shape and delegates to <ReservationList showBerth />.
- client-columns.tsx drops companyName column (TODO: add Yachts count +
Primary company once list endpoint joins those).
- client-filters.tsx drops isProxy filter.
- Wire realtime invalidations for yacht:ownership_transferred,
company_membership:added/ended, and berth_reservation:*.
