Physical disk monitoring is now disabled by default with a clear UI toggle for users who want to enable it.
**The Problem:**
Pulse was polling `/nodes/{node}/disks/list` every 10 seconds to check physical disk SMART data, causing idle HDDs to constantly spin up.
**The Solution:**
- Physical disk monitoring OFF by default (no HDD spin-up)
- New UI toggle in node edit modal under "Advanced monitoring"
- Clear warning: "This will cause HDDs to spin up from standby"
- When enabled, polls every 5 minutes (configurable via PhysicalDiskPollingMinutes)
- Storage pool monitoring (ZFS/LVM) still active and catches most disk failures
**UI Implementation:**
- Added monitorPhysicalDisks checkbox to PVE node settings
- Help text explains HDD spin-up behavior
- Field properly saved/loaded when editing nodes
- Only shown for PVE nodes (not PBS)
**Backend:**
- MonitorPhysicalDisks defaults to false
- Configurable polling interval (default 5 min)
- Interval-based polling with per-instance tracking
- Skips polls when interval hasn't elapsed
Users can now make an informed choice about disk monitoring vs. HDD power management.
