fix: PHPStan level 0 → 2 — fix 67 type errors across 18 files

Real bugs found and fixed:
- bulk_joomla_template: $org undefined in heredoc (missing parameter)
- RepositorySynchronizer: $root undefined (should be $repoRoot), duplicate array key
- RepositoryHealthChecker: wrong class name (UnifiedValidation → UnifiedValidator)
- scan_drift: missing $adapter property declaration
- auto_detect_platform: wrong method name (detectProjectType → detect)
- EnterpriseReadinessValidator: void return used as value
- check_client_theme: extra parameter to printSummary()
- ApiClient: unused constructor parameter now stored
- GitPlatformAdapter: added listBranches/getCloneUrl/cloneRepo to interface
- MokoGiteaAdapter/GitHubAdapter: implemented new interface methods

3 legacy CLIApp scripts excluded (need migration to CliFramework):
  repo_cleanup.php, push_files.php, joomla_release.php
