feat: member portal Sprint 8 — Member Directory

- GET /my/directory in MyService/MyController with q + interest filters
- Respects directoryVisible; excludes self; never exposes jid/phone
- q searches displayName/hometown/currentLocation (case-insensitive);
  interest filter via array `has`; aggregates top-20 interest filter chips
- BFF route forwards query string
- /my/directory page: server-rendered cards (avatar initials, location, interest tags)
- DirectorySearch client component: debounced search box + toggleable interest chips that drive URL params
- Directory nav item
