fix(mobile): support animated refs when opening Android chats

[khoi]

Opening an Android chat can throw Object is not a function when keyboard padding changes. The existing keyboard controller calls an animated ref as a function, while Reanimated 4.7 passes an object containing the native node.

Backport the mounted-node guard from the upstream fix, reported by bompus in keyboard-controller#1655. Both callable refs and object refs keep the unmounted-view check.

Verified by reproducing the failure in the Android API 35 development client, installing the patch, and opening the same chat successfully. Executed the patched callback with mounted and unmounted refs in both formats; all four cases passed. vp i applies the patch successfully.

Model: GPT-6-Astra. Harness: Codex.
