Remove version from dashboard header and fix commit hash tracking

- Remove version display from dashboard header for cleaner UI
- Keep /version endpoint for programmatic access
- Fix "commit hash unknown" issue by capturing git hash during Docker builds
- Update Dockerfile.fly to accept ANOMSTACK_BUILD_HASH build argument
- Modify deployment script to pass git commit hash to Docker build
- Update Makefile fly-build-test target to include git hash for local testing
