rosbridge config:
- rosbridge_params.yaml: add /saltybot/barometer, /vesc/left/state,
/vesc/right/state to topics_glob whitelist (were missing, blocked
the CAN monitor panel from receiving data)
- can_monitor.launch.py: new lightweight launch — rosbridge only,
whitelist scoped to the 5 CAN monitor topics, port overridable via
launch arg (ros2 launch saltybot_bringup can_monitor.launch.py port:=9091)
can_monitor_panel.js auto-reconnect:
- Exponential backoff: 2s → 3s → 4.5s → ... → 30s cap (×1.5 factor)
- Countdown displayed in conn-label ("Retry in Xs…") during wait
- Backoff resets to 2s on successful connection
- Manual CONNECT / Enter resets backoff and cancels pending timer
