fix(proxmox): address 11 dashboard issues and add missing VM action commands

Backend:
- Add resume_proxmox_vm, suspend_proxmox_vm, clone_vm, delete_vm Tauri commands
- Implement proxmox/vm.rs functions for resume, suspend, clone, delete operations
- Register all new commands in lib.rs

Frontend:
- Fix VMList.tsx: Import confirm from @tauri-apps/plugin-dialog
- Fix VMList.tsx: Replace prompt() with window.prompt() for user input
- Fix VMList.tsx: Correct paused VM action to resume instead of suspend
- Fix VMList.tsx: Implement proper menu positioning with horizontal overflow detection
- Fix StorageList.tsx: Add error handling to formatBytes for negative/non-numeric input
- Fix VMsPage.tsx: Remove redundant handler stubs, let VMList handle actions

All changes pass TypeScript type checking, Rust clippy, and frontend tests (386 tests passing).
