Move subscription QR bitmap generation from the synchronous share callback into the existing ViewModel, running CPU-bound encoding on Dispatchers.Default and exposing the completed bitmap through StateFlow.
Cancel pending result delivery when the dialog is dismissed, a newer share request replaces it, or the ViewModel is cleared. Keep dialog rendering lifecycle-aware and reuse the existing localized failure message when generation returns no bitmap.
Extract only QR generation and dialog-state wiring from local/talkback-all-10. Leave subscription row accessibility, custom actions, update handling, and clipboard sharing unchanged.
