fix(admin-web): remove double-upload on app version page

- Remove auto-parse on file select (was uploading 48MB twice, took 100+ sec)
- Backend /upload already parses APK internally, version fields are now optional
- Show file name + size after selection
- Show progress hint during upload
- Better error extraction from API response
- Clear error when new file is selected
