[Enhancement]: Ability to add username in user field

[Cyberes]

What features would you like to see added?

Currently, a user ID is set in the query. This user ID is just a bunch of random letters and numbers. Furthermore, it does not seem to be a per-user ID as every user sends the same string.

I need to track my users by their username. I would like to be able to do this through the custom endpoint config:

addParams:
  user:    'librechat-{{LibreChat_User_ID}}'

More details

I use Langfuse. The first row in the image below is the user ID that LibreChat is sending.

Which components are impacted by your request?
