downscaled to a standard edge.
* **Error Messages / i18n**
* Added localized error "Image format not supported: {format}".

## Summary by CodeRabbit
- New Features
- Delete icon added to AI session history with tooltip and confirmation
prompt; deleting current session opens a new session.

shows notifications.
- Improvements
- Cleanup now supports deleting sessions with or without a document ID
(document-specific or workspace-wide).
- UI tweaks for cleaner session item layout and safer click handling
(delete won’t trigger item click).

Fix issue [BS-2522](https://linear.app/affine-design/issue/BS-2522).
### Why make this change?
If the user data contains illegal content, carrying the user data in the system prompt will run the risk of having the account banned.
### What Changed?
- Move the `Context Documents` to the user prompt.
- Add `withPrompt` in `QueryChatHistoriesInput` options.
- Get chat histories without prompt messages.
- Omit document context when saving messages to the `aiSessionMessage` db.
