add expo-secure-store dependency and jest mocks

Adds expo-secure-store (~15.0.8, the SDK 54 bundled version) plus its
config plugin, which excludes the SecureStore keystore from Android
auto backup.

Also adds two global jest mocks: expo-secure-store, whose real entry
reads accessibility constants off the native module at import time, and
react-native-mmkv, since #/storage constructs an MMKV instance at module
scope. File-local mocks continue to take precedence.
