security(api): fix privilege escalation vulnerability in model config and chat message APIs (#25518)

The `ChatMessageApi` (`POST /console/api/apps/{app_id}/chat-messages`) and 
`ModelConfigResource` (`POST /console/api/apps/{app_id}/model-config`) 
endpoints do not properly validate user permissions, allowing users without `editor` 
permission to access restricted functionality.

This PR addresses this issue by adding proper permission check.
