Refactor: Unified pipeline execution, simplified UI, and fixed Docker config

- Backend: Refactored tasks.py to directly invoke run_single_fna_pipeline.py for consistency.
- Backend: Changed output format to ZIP and added auto-cleanup of intermediate files.
- Backend: Fixed language parameter passing in API and tasks.
- Frontend: Removed CRISPR Fusion UI elements from Submit and Monitor views.
- Frontend: Implemented simulated progress bar for better UX.
- Frontend: Restored One-click load button and added result file structure documentation.
- Docker: Fixed critical Restarting loop by removing incorrect image directive in docker-compose.yml.
- Docker: Optimized Dockerfile to correct .pixi environment path issues and prevent accidental deletion of frontend assets.
