fix: add fallback registries and improve deployment reliability

- Add fallback to official npm/PyPI registries when Chinese mirrors fail
- Fix dev workflow mirror host (127.0.0.1 -> 100.78.131.124)
- Add error handling and diagnostics to build steps
- Fix iPhone UI: make download/delete buttons always visible on mobile
- Add .dockerignore to reduce build context size
