fix: use default Apollo client for AI chat file upload

[a827681306]

Summary

Fix file uploads in AI chat (Agent Chat) failing with "Failed to upload file" for all file types.

Root Cause

useAIChatFileUpload.ts was using useApolloCoreClient() which points to the /graphql (workspace) endpoint. However, FileUploadResolver is decorated with @MetadataResolver(), meaning uploadFile is only registered on the /metadata endpoint.

Fix

Replace useApolloCoreClient() with useApolloClient() from @apollo/client, which is the default Apollo client pointing to the /metadata endpoint. This is consistent with how useUploadAttachmentFile.tsx handles file uploads.

Changes

• Replaced useApolloCoreClient import with useApolloClient from @apollo/client
• Updated the client variable to use the default Apollo client
• Removed unused useApolloCoreClient import

Fixes #18153

Greptile Summary

Fixed file upload failures in AI chat by switching from useApolloCoreClient() (which points to /graphql) to useApolloClient() (which points to /metadata). Since FileUploadResolver is decorated with @MetadataResolver(), it only registers the uploadFile mutation on the /metadata endpoint. This change aligns with the pattern used in useUploadAttachmentFile.tsx.

Confidence Score: 5/5

• Safe to merge - simple, focused bug fix with minimal code changes
• The fix is a straightforward client replacement that addresses the root cause (endpoint mismatch). The change is consistent with existing patterns in the codebase (useUploadAttachmentFile.tsx) and has been verified against the server-side resolver configuration.
• No files require special attention
