refactor: Refactor code to comply to basic principles

Fixes #65

Refactor code to comply with basic principles.

* **`monitor-app/main.py`**:
  - Split `check_and_update_status` into `fetch_status` and `update_status`.
  - Move GUI import logic to a separate function `import_gui_modules`.
  - Rename `setup_application` to `initialize_application`.
  - Update `main` to use the new functions.

* **`monitor-app/src/core/app_settings.py`**:
  - Split `AppSettings` into `SettingsLoader` and `SettingsSaver`.
  - Update `app_settings` to use the new classes.

* **`monitor-app/src/core/notification_handler.py`**:
  - Split event handling and notification sending into separate functions.
  - Rename functions for clarity, e.g., `send_game_online_notification` to `notify_game_online`.

* **`monitor-app/src/core/state.py`**:
  - Rename `get_state` to `retrieve_state` in `GameState` and `GameServerState`.
  - Rename `update` to `update_state` in `GameState` and `GameServerState`.

* **`monitor-app/src/core/steam_api.py`**:
  - Rename `get_status` to `fetch_status_from_api`.
  - Rename `get_game_icon` to `fetch_game_icon`.

* **`monitor-app/src/gui/mainwindow.py`**:
  - Rename `update_status` to `refresh_status`.
  - Rename `handle_status_timeout` to `on_status_timeout`.

* **`web-app/src/lib/services/webhook-service.ts`**:
  - Fix warning in `encryptWebhookUrl` by handling the error properly.
