Make temperature monitoring truly turnkey by automatically configuring
SSH ProxyJump when running in containers without pulse-sensor-proxy.
How it works:
1. Setup script runs on Proxmox host (e.g., delly)
2. Detects Pulse is containerized but proxy unavailable
3. Automatically configures SSH ProxyJump through the current host
4. Writes SSH config to /home/pulse/.ssh/config in container
5. Temperature monitoring "just works" without manual configuration
Changes:
- Track TEMP_MONITORING_AVAILABLE flag during proxy installation
- Auto-configure ProxyJump if proxy installation fails
- Add /api/system/ssh-config endpoint to write SSH config
- Only prompt for temperature monitoring if it can actually work
- Automatic SSH config: ProxyJump through Proxmox host
Before: User had to manually configure ProxyJump or install proxy
After: Temperature monitoring works automatically after setup script
This makes Docker deployments as turnkey as LXC deployments.
