Fix mobile sidebar swipe and drag failures (#2709)

* fix(app): prevent text selection during Android swipes

Gesture interception did not cancel the native view where the touch began, leaving Android's pending text-selection action alive.

* fix(app): restore iOS sidebar close swipes

Fabric could fail to attach close handlers when their target lived inside retained but display-hidden panel content. Keep a registered native gesture host mounted outside the presentation wrapper so close swipes work over nested lists without activating rows.

* fix(app): recover sidebar drags after cancellation

Cancelled native drags could leave a lifted row and the shared outer list locked. Scope terminal cleanup to the owning gesture session and release the lock on cancellation or unmount.

* test(app): clean up partial drag fixtures
