gsxdsm aa6d21eeca FN-7583: route Android back gesture through fusion:native-back so task detail returns to board ...

Fixes the Android predictive back-gesture (edge swipe) not returning from a task detail view to the board, even though the hardware/legacy Back button worked correctly.

- Patch the generated Android manifest post-sync to set android:enableOnBackInvokedCallback="true" on the <application> tag, opting into AndroidX's OnBackPressedDispatcher for predictive-back gesture completion (mitigating ionic-team/capacitor-plugins#2418 via the disableBackButtonHandler toggle shipped in @capacitor/app@7.1.0).
- Wire the patch script into Capacitor's capacitor:sync:after npm-script hook so it runs automatically after every cap sync (and therefore after cap run android / build:mobile).
- Ensure both the back gesture and the hardware Back button funnel through the same AndroidBackButtonManager backButton listener, dispatching the shared fusion:native-back event consumed by the dashboard's nav-history stack.
- Add regression coverage: a unit test for the manifest patch script's idempotent opt-in behavior, and a dashboard test asserting the task detail view returns to the board on fusion:native-back.
- Document the Android manifest patch rationale and the unchanged dashboard-side invariant in packages/mobile/README.md.
