Add comprehensive tests for new policy fields and combinations

Introduce tests to validate functionality for new policy fields, including `max_expiry_duration`, `protected_required`, `identifier_regex`, and `follows_whitelist_admins`. Also, cover combinations of new and existing fields to ensure compatibility and precedence rules are correctly enforced.

bump to v0.31.2
