feat(profile): role-aware nav + avatar menu + full editable profile

Navigation:
- UserMenu (avatar + role-aware dropdown: Dashboard, Admin Panel for admins,
  Profile, Sign out) replaces Sign In/Try Free when logged in (desktop + mobile).
- Real avatars in dashboard sidebar + a new admin-shell profile section.
- Shared Avatar primitive (image with initials fallback). SiteChrome excludes /admin.

Profile (data-collection surface for future AI video generation):
- SettingsProfile rebuilt: avatar upload + slogan, about, company, website,
  country, national code, birthdate, gender. No resume builder (per scope change).
- /api/profile forwards all fields; new user-scoped /api/profile/upload (avatar →
  MinIO via file-svc, sets avatar). Identity UpdateUserRequest/UserResponse widened
  (country/national/method); no DB migration (columns already exist).
- fa+en strings; verified GET/PATCH round-trip + logged-in SSR render.
