Can't upload a file with AskFileMessage when features.spontaneous_file_upload.enabled == False

[pmercier]

Describe the bug
When Spontaneous file upload is disabled we can't upload a file with AskFileMessage.

To Reproduce

1. Set features.spontaneous_file_upload.enabled = false in config.toml
2. use this basic code for file upload :

import json
import chainlit as cl  
@cl.on_chat_start
async def start():
    resp = await cl.AskFileMessage(content="Gimme a file", accept=["text/plain"]).send()
    await cl.Message(json.dumps(resp[0].__dict__)).send()

3. Run the code and upload a text file

Expected behavior
The config features.spontaneous_file_upload.enabled should impact only the file uploaded using the user message bar.

Screenshots
When trying to upload we are given this message in the GUI :

Desktop (please complete the following information):

Affect all browser

Smartphone (please complete the following information):
Affect all smartphone

Additional context
The GUI message is not clear. But the content found in the dev tool have more details :

detail: "File upload is not enabled"

Diving in the code we can see that the upload button use the same api endpoint (POST /project/file) than the spontaneaous upload.

This endpoint use the method chainlit.server.validate_file_upload() that check if the spontaneous_file_upload is enabled.

Nice catch, we are using the same method for both upload method. Will think about fixing this properly

Fixed in today's release. This is partial fix as the spontaneous file upload limits (like mime type or size) will also apply on top of the AskFileMessage limits.
