fix: remove 28 unused variables across frontend components

Cleaned up unused imports, state variables, and function parameters:
- CredentialsManager.tsx: removed 8 unused variables (Sheet/Select imports)
- FileManager.tsx: removed 10 unused variables (icons, state, functions)
- Terminal.tsx (Desktop): removed 5 unused variables (state, handlers)
- Terminal.tsx (Mobile): removed 5 unused variables (imports, state)

Reduced lint errors from 271 to 236 (35 errors fixed)
