fix(proxmox): comprehensive VM management and UI improvements

- VM Migration:
  * Added proper dialog with target node selection dropdown
  * Fixed migration trigger to actually call the API
  * Added live migration options with max downtime configuration

- VM Actions:
  * Fixed delete to use proper confirmation dialog
  * Fixed clone to calculate next available VMID automatically
  * Verified start/stop/shutdown/reboot/suspend/resume all work correctly

- VM Data Display:
  * Fixed VMList to properly map backend fields (mem, max_mem, max_disk)
  * All VM fields now display correctly (ID, Memory, Disk, CPU, Uptime)

- Network Management:
  * Added 'Add Interface' button with full dialog
  * Added Edit and Delete buttons for each interface
  * Form validation for interface creation

- Backup Management:
  * Fixed 'New Job' button to open creation dialog
  * Added form for creating backup jobs with schedule configuration

- Views:
  * Added graceful error handling for 501 Not Implemented
  * Shows user-friendly message when feature unavailable

- AI Provider:
  * Fixed system message ordering in openai.rs
  * Now combines all system messages and sends them at the beginning
  * Resolves 'System message must be at the beginning' error

- All 386 tests pass
