refactor: centralize permissions with context provider and remove redundant code

Improvements:
- Centralized permission state management in PermissionsProvider
  - Eliminates duplicate RPC calls across components
  - Single source of truth for permission state
  - Automatic HID re-initialization on permission changes
- Split exports into separate files for React Fast Refresh compliance
  - Created types/permissions.ts for Permission enum
  - Created hooks/usePermissions.ts for the hook with safe defaults
  - Created contexts/PermissionsContext.ts for context definition
  - Updated PermissionsProvider.tsx to only export the provider component
- Removed redundant getSessionSettings RPC call (settings already in WebSocket/WebRTC messages)
- Added connectionModeChanged event handler for seamless emergency promotions
- Fixed approval dialog race condition by checking isLoadingPermissions
- Removed all redundant comments and code for leaner implementation
- Updated imports across 10+ component files

Result: Zero ESLint warnings, cleaner architecture, no duplicate RPC calls, all functionality preserved
