fix: crash al dictar por closures de callbacks aislados al main actor

Browse Source 
Crashlytics: dispatch_assert_queue_fail en com.apple.root.default-qos, dentro de
closure #1 in SpeechDictationService.start, llamado desde __TCCAccessRequest.

El proyecto compila en Swift 6 (activo desde febrero, antes del dictado). Los
callbacks de APIs ObjC pre-concurrency escritos dentro de este tipo @MainActor se
infieren aislados al main actor, y Swift 6 inserta una comprobacion de aislamiento
al entrar. TCC invoca el handler en cola de fondo, la comprobacion falla y mata el
proceso. El Task { @MainActor } de dentro no ayuda: el crash es antes de llegar.

Cuatro sitios con el mismo patron, tres enmascarados detras del primero porque
nadie pasaba de los permisos:

- requestAuthorization y requestRecordPermission -> wrappers nonisolated con
  continuation, el handler deja de estar aislado
- recognitionTask -> closure @Sendable explicito; solo cruzan valores Sendable
  porque SFSpeechRecognitionResult no lo es
- installTap -> captura el request local en vez de ir por self, que el hilo de
  audio en tiempo real no debe tocar estado del main actor

requestAuthorization llama al handler aunque el permiso ya este concedido, asi
que afectaba tambien a usuarios recurrentes: el dictado probablemente no ha
funcionado nunca desde la 2.0.

Los tests que acompanan NO reproducen el crash: el simulador entrega el callback
sincrono en el hilo principal y el codigo previo pasa igual. Comprobado
revirtiendo el fix. Queda pendiente validarlo en dispositivo real.
