feat: improve Docker build with version selection and remove fallback mechanism (#185)

- Add version input parameter to docker.yml workflow_dispatch
- Support main-latest, latest, dev-xxx, and specific version patterns
- Remove complex fallback mechanism from all Dockerfile variants
- Add clear error handling with helpful user guidance
- Create main-latest versions for development builds
- Ensure Docker builds require explicit VERSION parameter
- Update all Docker variants (production, alpine, ubuntu) consistently

This change solves the build dependency issue where Docker builds
could fail when expected binary artifacts don't exist, by providing
a clean version selection mechanism without unpredictable fallbacks.
