feat: implement server logging and event hook features

- Introduced server log level configuration and HTTP request logging settings, allowing users to control the verbosity of server logs and enable or disable request logging at runtime.
- Added an Event Hook Service to execute custom actions based on system events, supporting shell commands and HTTP webhooks.
- Enhanced the UI with new sections for managing server logging preferences and event hooks, including a dialog for creating and editing hooks.
- Updated global settings to include server log level and request logging options, ensuring persistence across sessions.

These changes aim to improve debugging capabilities and provide users with customizable event-driven actions within the application.
