refactor: eliminate duplicate control files and consolidate to capabilities/

- Removed duplicate control files from testdrive-jsui/static/js/controls/
- Removed duplicate control files from markitect/static/js/controls/
- Updated all references to point to capabilities/testdrive-jsui/js/controls/
- Fixed relative paths in test files and templates
- Consolidated to single source of truth in capabilities directory
- Updated plugin configuration and documentation references

This eliminates confusion and ensures all systems use the most recent
control implementations from the capabilities directory.
