ci: Run deploy on host instead of container for network access

Build improvements:
- Enable ccache via IDF_CCACHE_ENABLE=1
- Mount /var/cache/ccache volume for persistent cache
- Show ccache stats after build

Deployment improvements:
- Deploy to all sensors in parallel (max 3)
- Reduced total deploy time from ~2.5min to ~1min

Note: Runner needs /var/cache/ccache directory with write permissions
