Add CACHE_STATUS UART poll and dashboard live stream.

Combine cached accel and tap in one low-overhead master command for ~16 ms host polling. The dashboard uses a single live-stream toggle plus per-slave accel-stream controls; fix live_stream state so polling is not cleared every slow client refresh. Co-authored-by: Cursor <cursoragent@cursor.com>
