PPOP-242 [gateway] [api-v1] fix: solve file upload issue for big files

[thomasAtCoopengo]

Fix #PPOP-242

Description

Issues in uploading large files through b2b and b2c.

Has this been tested ?

Yes, locally with a nevidis-recette environment.
In env.custom, add the following lines (example if we need to handle files as large as 30mb):

# Use this variable to fix the limit size of files passed through the gateway
MAX_LIMIT_FILE_SIZE_UPLOAD=30

# Use this to fix the max size of files passed to the API-v1 (coog-web)
COOG_API_PAYLOAD_LIMIT=30mb

As these env vars are already implemented in the code, making sure to use the right values for each customer will solve the issue encountered.

Tests have been conducted locally with the files attached here:
