## Summary
- rebuild the authenticated shell, device dashboard, device detail pages, scenes, activity timeline, account sheet, and settings experience
- redesign infrared remote management and controls, including custom remotes, learn-state handling, slot isolation, and safe default content
- add persisted theme controls with internal accent, color-style, and color-standard resolution while keeping dynamic color authoritative
- add ABox profile defaults for the three exact gateway device names, editable starter scenes, and custom infrared remotes
- persist real activity events for device commands, infrared actions, and scene execution
- stabilize navigation and back behavior, including duplicate top-back protection and removal of the unfinished predictive-back option
- update launcher icons and bilingual application name
## Verification
- `:android:app:assembleDebug`
- installed the debug APK on `emulator-5554`
- manually exercised device detail navigation, settings/theme navigation, infrared management, activity records, and repeated back actions
## Notes
- no automated test suite was run during the visual iteration cycle
- `docs/superpowers/**` and local reference repositories are excluded from this PR
