Subject: [PATCH] Add per-node temperature monitoring and fix critical config
 update bug

This commit implements per-node temperature monitoring control and fixes a critical
bug where partial node updates were destroying existing configuration.

Backend changes:
- Add TemperatureMonitoringEnabled field (*bool) to PVEInstance, PBSInstance, and PMGInstance
- Update monitor.go to check per-node temperature setting with global fallback
- Convert all NodeConfigRequest boolean fields to *bool pointers
- Add nil checks in HandleUpdateNode to prevent overwriting unmodified fields
- Fix critical bug where partial updates zeroed out MonitorVMs, MonitorContainers, etc.
- Update NodeResponse, NodeFrontend, and StateSnapshot to include temperature setting
- Fix HandleAddNode and test connection handlers to use pointer-based boolean fields

Frontend changes:
- Add temperatureMonitoringEnabled to Node interface and config types
- Create per-node temperature monitoring toggle handler with optimistic updates
- Update NodeModal to wire up per-node temperature toggle
- Add isTemperatureMonitoringEnabled helper to check effective monitoring state
- Update ConfiguredNodeTables to show/hide temperature badge based on monitoring state
- Update NodeSummaryTable to conditionally show temperature column
- Pass globalTemperatureMonitoringEnabled prop through component tree

The critical bug fix ensures that when updating a single field (like temperature
monitoring), the backend only modifies that specific field instead of zeroing out
all other boolean configuration fields.
