- Display client key and server key on Settings app cards with toggle
  visibility and copy button
- Hide API keys table in Desa Mandiri Keys tab behind toggle + copy
- Add eye toggle to password inputs in Add App and Edit API Config
  modals
- Backend now returns apiKey and clientApiKey in apps list endpoint
