feat: adopt new backend api for attachment (#13336)

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

## Summary by CodeRabbit

* **New Features**
* Introduced a new query for applying document updates using AI,
allowing merged markdown responses.
* Added support for an optional file upload field when creating chat
messages.

* **Improvements**
* Enhanced recent Copilot sessions query with pagination by adding an
offset parameter.
* Refined attachment handling in chat responses to better distinguish
between single and multiple file uploads, improving reliability.

* **Bug Fixes**
  * Minor update to error handling for clearer messaging.

* **Chores**
* Cleaned up and updated iOS project configuration files for improved
build consistency.
