Wheel report template: add P6, OS-agnostic phone field

- Add InMotion P6 to the wheel dropdown
- Rename 'Phone model + Android version' to 'Phone model + OS version'
  so the placeholder Android example doesn't imply iOS users (or future
  Wear / desktop ports) are excluded
- Map 'P6' in the wheel name to the new dropdown option in the banner
- Drop em-dash from the form description
