Enhancement: allow setting model parameter ranges for custom endpoints

[happyZYM]

What happened?

I would like to set temperature above 1.0(For example, deepseek https://platform.deepseek.com/api-docs/quick_start/parameter_settings/), but LibreChat rejected my operation.

Steps to Reproduce

1. click on the configure panel
2. set temperature to 1.3
3. the system automatically set temperature to 1.0

What browsers are you seeing the problem on?
