Merge branch 'main' into ui-refactor

Resolve conflicts and complete the profile display-name -> ID migration
across the daemon, CLI, UI services, tray, and React frontend.

- Regenerate client/proto daemon.pb.go from the merged proto so it carries
  both branches' RPCs (ui-refactor: SubscribeStatus/RegisterUILog/ExtendAuthSession,
  main: RenameProfile + id fields); keep the v6.33.1 generator header
- server.go: combine ui-refactor's profile-list-changed events with main's
  id-bearing responses; publish profile-list-changed on rename
- Drop the deleted Fyne client_ui.go/profile.go and port main's profile-ID
  changes into the refactored services/tray
- UI services, tray and React: send the profile ID as the daemon handle and
  keep the display name for rendering only (activeProfileId vs activeProfile)
- Relax the profile-name input to match the daemon's sanitizeDisplayName
  (spaces, emoji, any valid UTF-8); cap at 128
- Expose RenameProfile via a Profiles.Rename services wrapper (+ regenerated
  bindings) for the frontend to wire up
- cmd/login.go: use the profile ID for GetProfileState
