- MainScreen: add missing Surface import (polished screen switched to Scaffold and dropped it; FinderScreen uses Surface) — was the compile break.
- TrackerRinger: real multi-protocol play-sound from AirGuard's verified source: AirTag native (single 0xAF byte, self-disconnects = success via status 19), DULT (0x0300, enable indications first), Find My legacy fd44 (enable notifications, [0x01,0x00,0x03]); tried in priority order by which service the tag exposes. Samsung SmartTag + Tile have no non-owner ring path -> tell the user to use SmartThings / the Tile app. API-version-aware characteristic + descriptor writes.
