fix(windows): wire Helix page to live AI settings source

Helix (/integrations/helix) is PageContainer + AISettings (provider/key/model, ~60 per-feature opt-in toggles, restore panel, usage/cost card) but was registered with EmptyAiSettingsSource so it rendered blank (read as 'just basic'). Register HelixPage with the live AiSettingsSource(api, engine, options) so it shows the real AI configuration surface.
