fix(trial-execution): handle SSH actions without requiring ROS connection

- Add startTime parameter to executeRobotActionInternal for proper duration tracking
- SSH actions (animations, posture commands) now work without ROS bridge connection
- Refactor executeAction to handle SSH and ROS paths separately
