feat(tor): desktop Tor settings UI — indicator, toggle, dialog

Phase 5: Desktop settings UI for Tor.

TorStatusIndicator:
- Shield icon in sidebar footer (gray/yellow/green/red)
- Tooltip shows status (no port number for security)
- Only visible when Tor is not Off

TorSettingsSection:
- Inline in settings screen between Media Server and Dev Settings
- Mode selector (Off/Internal/External) with segmented buttons
- External SOCKS port input with validation (1-65535)
- "Advanced..." button opens full dialog

TorSettingsDialog:
- Full DialogWindow with preset selector (radio buttons)
- 4 relay routing toggles + 7 content routing toggles
- Preset auto-detection (whichPreset)
- Save/Cancel with DesktopTorPreferences persistence
