refactor(tray): remove copy-token clipboard feature

Dashboard login now uses standard web auth (bcrypt + session cookie).
The system tray 'Copy dashboard token' menu item is no longer needed.

- Delete tray_offers_copy.go and tray_offers_copy_stub.go
- Remove mCopyTok menu item and clipboard handler from systray.go
- Remove launcherDashboardTokenForClipboard var from main.go
- Remove MenuCopyToken/MenuCopyTokenHint keys from i18n.go
