⚙️ fix: File Config Handling (#4664)

Browse source 
* chore: typing

* refactor: create file filter from custom fileConfig, if provided

* refactor: use logger utility to avoid overly verbose axios error logs when using RAG_API

* fix(useFileHandling): use memoization/callbacks to make sure the appropriate fileConfig is used; refactor: move endpoint to first field applied to formdata

* chore: update librechat-data-provider version to 0.7.54

* chore: revert type change
