fix: add cache clearing and cache-busting to Dockerfile

- Add explicit cache clearing for .docusaurus and build directories
- Add build arguments (BUILD_DATE, BUILD_VERSION) to force Docker layer cache invalidation
- This ensures clean builds without cached artifacts from previous builds
- Should resolve persistent ProgressPanel component errors
