2 - Granular Access Permissions to Admin Panel

[jrcastro2]

Introduce a mechanism to restrict access to specific admin panel sections. First use case: CERN Library should access only the harvester job log page, without access to other admin functionalities. The mechanism should be generic and reusable for future sections.

Tasks:

• Implement permission checks for specific admin panel sections.
• Restrict access so that Library can access only harvester job logs.
• Ensure mechanism is reusable for other sections.
• Update UI to correctly hide/show restricted sections.
