fix: Add container readiness wait after spawn

Browse Source 
After spawning a new container, wait until it's fully started and services
are ready before returning to the frontend. This prevents race conditions
where the frontend opens the container URL before the service is ready.

Solution: Wait loop (max 30s) for container.status == 'running',
then additional 2s for service startup (code-server, PlatformIO, etc).

This fixes the 404 error when opening a freshly spawned container.
