feat(yachts): list + owner-scoped list + autocomplete

Adds `listYachts`, `listYachtsForOwner`, and `autocomplete` to the
yacht service so UIs can page/filter yachts per port, look up all
yachts tied to a given client/company, and power search-as-you-type.

`listYachts` delegates to the shared port-scoped `buildListQuery`,
supporting search over name/hullNumber/registration plus ownerType,
ownerId and status filters; `autocomplete` caps at 10 results and is
tenant-scoped; `listYachtsForOwner` returns all yachts whose current
owner matches, newest first. Extends `makeYacht` factory to accept
flat `name`, `status`, `hullNumber`, `registration` overrides.
