Fix 21 bugs: build failures, broken pages, IPC mismatches, and missing error handling

Critical fixes:
- Add esbuild dependency and fix Vite build target (safari13 → es2022)
- Fix StorageDetail always failing (null node parameter)
- Fix VNC/Terminal console stuck on 'Connecting...' (add onConnected callback)
- Fix Ctrl+Alt+Del not working (add data-vnc attribute and event listener)
- Add serde(rename_all='camelCase') to all 27 Rust structs crossing IPC
- Fix login methods returning empty connection_id (generate from URL hash)
- Fix add_connection not storing connections in HashMap
- Fix keyring_entry panicking on failure (replace expect with map_err)

High-severity fixes:
- Fix refresh_ticket reading wrong keyring entry for username
- Add onError handlers to all 23 mutations (toast notifications)
- Fix stale closure on activeConnectionId (use getState() instead)
- Fix WebSocket listener teardown race condition
- Add WebSocket reconnection retry limit (max 10 attempts)

Medium-severity fixes:
- Add Settings navigation to CommandPalette (Cmd+K)
- Disable dead Nodes/Containers sidebar items
- Wire up HardwareTab save button with warning toast
- Wire up QuickActions navigation buttons
- Add Dashboard error state (was stuck on 'Loading...')
- Add default case to App.tsx view switch
- Extract formatBytes/formatUptime/formatNetworkRate to shared utility
- Fix formatBytes negative input bug
