Refactor: consolidate workflow, dynamic SQLite permission fix

Refactor: consolidate workflow, dynamic SQLite permission fix This commit consolidates the Docker build and test workflow into a single file (`docker-buildx.yml`), ensuring images are tested before being pushed. It also implements a robust solution for Drupal SQLite installation permissions. Key changes: - **Workflow Consolidation:** - `docker-buildx.yml`: Merged logic from `test-drupal.yml`. Uses `load: true` for testing and `push: true` on success. - `test-drupal.yml`: Deleted. - **Robust Drupal Installation (`tests/install-drupal.sh`):** - Accepts explicit version constraints (`^10`, `^11`) to prevent PHP/Drupal version mismatches. - Corrected SQLite connection string to remove `localhost` (`sqlite://sites/default/files/.ht.sqlite`). - **Dynamic Permission Fix:** Parses `drush status --format=json` to find the exact location of the SQLite database and `chmod 777` its directory, ensuring the web server can write to it during tests. - **Improved Verification (`tests/verify-drupal.sh`):** - Updated debugging logic to dynamically find the SQLite database via Drush and log its specific permissions, rather than listing generic directories. - **Image Compatibility (`php8/apache-bookworm/Dockerfile`):** - Added `SQLITE_ENABLE_COLUMN_METADATA=1` to support Drupal requirements.
