- Replace inline integrations tab with link to /settings/integrations
- Remove ~1500 lines of duplicated integration UI from settings
- Remove duplicated integration event handlers from settings_live
- Standalone IntegrationsLive page remains the single source of truth
- Settings page down from ~2400 to ~900 lines
