Support Editing and Deleting Registered Data Sources

Implement functionality to allow users to edit and delete registered data sources, improving management and cleanup of data source configurations.

Current Behavior:

• Once a data source is registered, it cannot be modified or removed through the UI or API.

Expected Features:

1. Edit Data Source:

   • Update properties such as name, connection details, or credentials.
   • Validate inputs to prevent misconfiguration.

2. Delete Data Source:

   • Remove unused or obsolete data sources.
   • Provide confirmation prompts to avoid accidental deletion.
   • Consider handling or warning about dependent applications or data.

Tasks:

• Add UI controls for editing and deleting data sources.
• Create corresponding backend API endpoints (PUT /data-sources/{id}, DELETE /data-sources/{id}).
• Implement validation and permission checks.
• Handle potential cascading impacts or restrict deletion if dependencies exist.

Benefits:

• Enhances flexibility in managing data sources.
• Keeps configuration clean and up-to-date.
• Supports better system hygiene and administration.
