feat(ios): ai button feature flag (#13280)

<!-- This is an auto-generated comment: release notes by coderabbit.ai
-->

## Summary by CodeRabbit

* **New Features**
  * Added a global API to check the AI button feature flag status.

* **Bug Fixes**
* Improved handling for the AI button feature: the app now checks the
feature flag before proceeding and provides a clear error if the feature
is disabled.

* **Refactor**
  * Removed all AI button presentation and dismissal logic from the app.
* Deleted unused plugin interfaces and registration related to the AI
button feature.

* **Chores**
  * Updated project metadata and build configuration for iOS.
