features: add commit and push option to git commit window

- Add split button with dropdown in commit dialog supporting both
  "Commit" and "Commit and Push" actions
- Pass folderId through gitCommit/gitPush API calls so backend emits
  events that the folder window can receive for toast notifications
- Update Tauri git_commit and git_push commands to accept folder_id
  parameter with window label fallback for cross-window compatibility
- Wrap commit page with GitCredentialProvider for push authentication
- Keep commit window open when push fails so user can see the error
- Add i18n translations for all 10 locales
