refactor(src/commands): Refactor battery and touchpad command execution

Refactored command flow to separate daemon invocation, added status handling, and improved error handling.

- New Features: Added `execute_local` helper and `BatteryCommands::Status` handling.
- Enhancements: Simplified daemon checks, removed redundant condition, improved readability and error messages.
- Bug Fixes: Fixed missed daemon return path for status command and ensured proper touchpad inhibition logic.
