T8b949e/**

* Tests for [KableMeshtasticRadioProfile] — the GATT characteristic orchestration layer.

*

* Uses [FakeBleService] from `core:testing`. Since [FakeBleService] inherits the default [BleService.observe] overload

* (which invokes `onSubscription` via `onStart`), `awaitSubscriptionReady()` completes immediately — matching the

* behaviour expected from non-Kable implementations.
