openScale-port: GPL-3.0-relicens + BT-vågsdrivrutiner (grund + Exingtech Y1/VScale)

- LICENSE → GPL-3.0 (krav för att bädda in openScales kod)
- Vendrat com.health.openscale.core.bluetooth: ScaleDeviceHandler,
  Gatt/Broadcast/Spp-adaptrar, ScaleFactory (utan Hilt), ScaleCommunicator,
  BleScanner, ConverterUtils, ScaleMeasurement/ScaleUser — copyright-headers kvar
- ExingtechY1Handler: Biltema 84-1002 (PT-727), annonserar som "VScale"
- Shims för openScales interna beroenden: facades (DataStore-backade),
  slimmade enums/User/MeasurementWithValues, LogManager → logcat
- blessed-kotlin 3.0.12 via JitPack; Kotlin 2.0.21→2.2.0, KSP2, Room 2.7.2
- BLE-permissions (BLUETOOTH_SCAN neverForLocation + CONNECT) i manifestet
- Svenska strängresurser för drivrutinernas meddelanden
