## Summary
- replace the crowded add-remote dialog with a full-screen three-step flow
- make the first step explicitly choose between adding from the infrared library and creating through learning
- add a full-screen remote editor with read-only library configuration, editable custom layouts, and delete confirmation
- append newly created remotes to the bottom of the management list and right side of the remote switcher
- remove the fan emoji from the device type label
- add a curated CC0 Flipper-IRDB preset subset with real NEC/NECext protocol codes
- add projector, audio/receiver, set-top box, streaming device, and lighting categories
- require a test power command and explicit device-response confirmation before creating library remotes
- include source attribution and a repeatable converter for parsed NEC/NECext signals
## Compatibility scope
- imported formats: parsed NEC and NECext only
- excluded: raw pulse data and other protocols because the ABox irCode encoding contract is not publicly specified for them
- existing devices, remotes, and scenes are not migrated or renamed
## Verification
- ./gradlew.bat :android:app:assembleDebug --no-daemon
- converter reproduced
