🔧 TDD Support: Enhanced Mock Providers & Policy Validation

Supporting changes for full IAM integration:

✅ ENHANCED MOCK PROVIDERS:
- LDAP mock provider with complete authentication support
- OIDC mock provider with token compatibility improvements
- Better test data separation between mock and production code

✅ IMPROVED POLICY VALIDATION:
- Trust policy validation separate from resource policies
- Enhanced policy engine test coverage
- Better policy document structure validation

✅ REFINED STS SERVICE:
- Improved session management and validation
- Better error handling and edge cases
- Enhanced test coverage for complex scenarios

These changes provide the foundation for the integrated IAM system.
