[Bug]: Agents - multi file upload erratic behaviour

[thingersoft]

What happened?

Attaching multiple files at once in "file search" functionality causes erratic behaviour: the number of uploaded files doesn't match the number of selected files.

Steps to Reproduce

1. configure RAG
2. configure an agent
3. enable file search for the agent
4. select 5 documents to upload at once
5. repeat step 4
6. repeat step 4

You'll and up with n.13 documents associated with the agent

That's a concurrency issue.
Attaching multiple files at once triggers one request for each file.
On server side the agent update logic includes two async operations, one to retrieve the agent and the following to update it based on the previously retrieved data.
With multiple concurrent requests being processed the retrieved data can become stale, causing the reported issue.
