Fix git pull conflicts with pull.ff=only and improve commit UX

- Replace git pull with fetch + merge to avoid conflicts with global
  git config (e.g. pull.ff=only) and background fetch --all
- Disable commit/commit+push buttons when message is empty
- Always show Push/Pull menu items even without remotes configured
- Default remote name to 'origin' when adding a new remote
