fix: add system permissions handler for diagnostics and repair

- Implemented SystemPermissionsHandler to check and repair file permissions.
- Added endpoints for retrieving and repairing permissions.
- Introduced utility functions for permission checks and error mapping.
- Created tests for the new handler and utility functions.
- Updated routes to include the new permissions endpoints.
- Enhanced configuration to support new logging and plugin directories.
