Implements Task 5.3: server page passes yachtId to a client YachtDetail,
which fetches via TanStack Query and renders the shared DetailLayout with
Overview / Ownership History / Interests / Reservations / Notes / Tags
tabs. Header shows name, dimensions, polymorphic owner link, status badge,
and Edit / Transfer / Archive actions. Transfer is a stub dialog pending
Task 5.5; Notes tab is a placeholder because NotesList does not yet support
entityType='yachts'.
