Address code review suggestion from @jonpspri:

Problem: The _has_permission static method handles *, admin.*, and exact
matches but had no dedicated tests covering edge cases.

Solution:
- Added 5 comprehensive wildcard permission tests
- Tests cover: exact match, *, namespace.*, multiple permissions
- Discovered and fixed bug: admin.* incorrectly matched 'admin'

Bug Fixed:
- admin.* should only match admin.SOMETHING (e.g., admin.system_config)
- It should NOT match just 'admin' (no dot)
- Fixed by removing 'required == prefix' check
- Now correctly requires dot: required.startswith(prefix + '.')

Test Coverage:
✅ test_exact_match - exact permission matching
✅ test_wildcard_star_matches_all - * matches everything
✅ test_namespace_wildcard - admin.* matches admin.anything
✅ test_wildcard_does_not_match_namespace_only - admin.* ≠ admin
✅ test_multiple_permissions - combined permission lists

All 21 PolicyEngine tests passing (16 existing + 5 new).
