This commit adds a new endpoint `/upgrade` to upgrade a Wazuh agent in the `agents.py` file. The endpoint requires the `agent_id` as a parameter and upgrades the corresponding agent. The upgrade process may take a few minutes to complete. This feature improves the functionality of the application by allowing users to easily upgrade Wazuh agents.

This commit adds a new endpoint `/purge` to the `monitoring_alert.py` file. The endpoint allows users with admin or analyst scopes to purge all monitoring alerts from the database. It retrieves all monitoring alerts, deletes them from the database, and returns the purged alerts in the response. This feature improves the functionality of the application by providing a convenient way to remove all monitoring alerts when needed.

This commit updates the URL for the delete endpoint in the `monitoringAlerts.ts` file. The previous URL was `/monitoring_alert/{alertId}`, and it has been changed to `/monitoring_alert/single_alert/{alertId}`. This change improves the clarity and consistency of the endpoint URL, making it more descriptive and aligned with the purpose of the endpoint.

This commit updates the `get_current_process_names` function in the `wazuh.py` file. The function now uses the `get` method with default values to safely retrieve the `process_name` from the alert context. This change improves the robustness of the function and ensures that it returns an empty list if the necessary data is not available.
