Harden Go2 LAN teleop setup

Stack:

1. Add Go2 local Wi-Fi doctor dimensionalOS/dimos#2378 - Add Go2 local Wi-Fi doctor
2. Add blueprint preflight hooks #1 - Add reusable blueprint/hardware preflight infrastructure
3. Autodetect Go2 startup connectivity #2 - Apply startup preflights to Go2 connectivity
4. This PR - Harden Go2 LAN teleop/browser setup

Summary:

• Add phone and Quest LAN UI preflights that warn when motion-capable browser UIs are loopback-only, without auto-exposing them to the LAN.
• Keep --listen-host 0.0.0.0 explicit for control UI exposure on trusted local networks.
• Serve phone and Quest browser payloads locally as JSON instead of relying on CDN @dimos/msgs resolution.
• Accept legacy binary LCM payloads and JSON payloads in phone/Quest teleop modules.
• Make Quest Joy decoding tolerate missing optional buttons while keeping axes strict.
• Publish decoded Go2 teleop cmd_vel from JSON and binary paths.
• Generate SAN-aware local HTTPS certificates for teleop clients under DimOS state.
• Improve Rerun/dashboard serving paths and add web/server tests.
• Add a Go2 local Wi-Fi teleop troubleshooting guide and docs navigation entry.

Why:

• Startup autodetection gets the robot connection right; this branch makes the local browser control path work reliably without silently broadening network exposure.
• Phone/Quest teleop should be self-contained on an operator LAN, including offline/local browser loads.
