🧪 test: implement Phase 2 BDD infrastructure with synchronization, context management, and tag-based execution

- Added synchronization helpers (waitForServerReady, waitForConfigReload, etc.)
- Implemented feature-specific context management (AuthContext, ConfigContext)
- Created feature suite initialization (InitializeFeatureSuite, CleanupFeatureSuite)
- Added comprehensive tag-based test execution with @smoke, @critical, @basic tags
- Enhanced run-bdd-tests.sh with list-tags and run [tags] subcommands
- Added BDD_TAGS.md documentation for tag usage
- Maintained backward compatibility with existing test structure
