fix(ios): restore LiveDrawWidget identity after apple-targets 5 regeneration

The SDK 56 prebuild derived the widget bundle id from its folder name
(com.sauci.app.widget) and pointed CODE_SIGN_ENTITLEMENTS at the ignored
ios/.targets cache. Restore the shipped com.sauci.app.LiveDrawWidget
identity, the tracked entitlements file, and pin bundleIdentifier in the
target config so future prebuilds keep it.
