* add K8S note in README, fix broken e2e

* feat/upload-bar (#30)

* feat/upload-bar: add a upload bar when user upload file, indicate the upload process

* feat/save-loading-status: add save status when click back button from editor

* fix: address PR review issues in upload and save features

- Replace deprecated substr() with substring() in UploadContext
- Fix broken error handling that checked stale task status
- Fix missing useEffect dependency in UploadStatus
- Fix CSS class conflict in progress bar styling
- Add error recovery for save state in Editor (reset on failure)
