Add Docker Compose PX4 SITL, ROS 2, Foxglove, DDS, and MAVROS stack

[cdenihan]

Summary

This PR adds a Docker-based runtime for MAVInsight with PX4 SITL, ROS 2 Humble, Foxglove Bridge, Micro XRCE-DDS Agent, and MAVROS.

Changes

• Adds a ROS 2 Docker image that installs:
  • MAVInsight runtime dependencies
  • px4_msgs
  • foxglove_bridge
  • mavros, mavros_extras, and mavros_msgs
  • Micro XRCE-DDS Agent
• Adds a PX4 wrapper image and entrypoint so:
  • QGroundControl can connect without Docker binding 14550/udp
  • PX4 uXRCE-DDS connects to the ROS container’s local Micro XRCE-DDS Agent
• Updates docker-compose.yml to run PX4 and ROS together.
• Runs these ROS processes concurrently:
  • MicroXRCEAgent udp4 -p 8888
  • ros2 launch mavros px4.launch ...
  • ros2 launch mavinsight launch_all_vehicles_no_tba.launch.py
  • ros2 launch foxglove_bridge foxglove_bridge_launch.xml
• Makes MAVROS configurable through environment variables:
  • START_MAVROS
  • MAVROS_NAMESPACE
  • MAVROS_FCU_URL

Validation

• Confirmed Docker Compose config is valid.
• Confirmed QGroundControl connects after removing the 14550/udp host bind.
• Confirmed PX4 publishes /fmu/out/... topics through DDS.
• Built the ROS image successfully with MAVROS and GeographicLib datasets installed.
• NOTE: All code tested on macOS
