bench mode: live camera via thermald, blinking telemetry indicator

- Unblocked thermald and camerad — thermald manages CPU cores and reads
  fake pandaStates for ignition, bench no longer publishes deviceState
- camerad starts with live camera feed on bench
- Force nvg->update() every frame for HUD repaint without camera dependency
- Blue blinking telemetry circle uses getBool pattern
- camerad debug logging for startup diagnostics
