chore: enhance ACL handling in dropdowns and add emergency token flows

- Add tests to normalize string numeric ACL IDs in AccessListSelector.
- Implement regression tests for ProxyHostForm to ensure numeric ACL values are submitted correctly.
- Introduce a recovery function for ACL lockout scenarios in auth setup.
- Create new tests for ACL creation and security header profiles to ensure dropdown coverage.
- Add regression tests for ACL and Security Headers dropdown behavior in ProxyHostForm.
- Establish a security shard setup to validate emergency token configurations and reset security states.
- Enhance emergency operations tests to ensure ACL selections persist across create/edit flows.
