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
