feat(providers): group presets into sponsors and non-sponsors

- Original sort mode now shows official > prime partner > sponsors
  (preset file order, aligned with the README sponsor table) >
  non-sponsors sorted by display name
- Physically reorder sponsor entries in all 8 preset files to match
  the README sponsor table order; add group marker comments
- Drop stale section comments in openclaw/hermes preset files
- Update ProviderPresetSelector tests for the new ordering
