bot: fix slow/unsteerable driving + controls tooltip

Diagnosis (agent + live values): tuning & tread geometry were fine, debugAutoDrive
off — the real drag was the box chassis sliding on default ~0.6 friction, which ate
forward speed AND resisted yaw (dead steering).
- Bot_LowFriction physics material (0.3, Minimum combine) on the chassis → slides +
  yaws freely.
- TreadPart yaw-assist (220 N·m, sign reinforces natural differential) so a throttle
  difference gives a clear turn; cancels to zero on equal throttle (straight kept).
- SeatManager: context-aware controls tooltip under the seat box (on-foot vs driving),
  with a 'turn: differ vs teammate' hint.
