fix(tui): address remaining review feedback — ordering and digit shortcuts

- Emit providers in CANONICAL_PROVIDERS order (matching hermes model)
  with user-defined/custom providers appended after
- Remove digit quick-select (1-9,0) handler — inconsistent with
  absolute row numbering and already removed from hint text
- Remove unused windowOffset import
