fix: reset models.Setting struct to prevent ID leakage in queries

- Added a reset of the models.Setting struct before querying for settings in both the Manager and Cerberus components to avoid ID leakage from previous queries.
- Introduced new functions in Cerberus for checking admin authentication and admin whitelist status.
- Enhanced middleware logic to allow admin users to bypass ACL checks if their IP is whitelisted.
- Added tests to verify the behavior of the middleware with respect to ACLs and admin whitelisting.
- Created a new utility for checking if an IP is in a CIDR list.
- Updated various services to use `Where` clause for fetching records by ID instead of directly passing the ID to `First`, ensuring consistency in query patterns.
- Added comprehensive tests for settings queries to demonstrate and verify the fix for ID leakage issues.
