Delete an endpoint-to-action mapping from the system.
Authorization: Requires admin privileges to delete mappings.
Impact: Deleting a mapping will remove authorization requirements for the corresponding endpoint. Requests to that endpoint will no longer be checked against the associated action.
Idempotent Operation: Attempting to delete a non-existent mapping returns success (204) for idempotent behavior.
Use Cases:
Warning: Ensure the endpoint should no longer require authorization before deleting its mapping.
