Litellm router code coverage 3 (#6274)
* refactor(router.py): move assistants api endpoints to using 1 pass-through factory function

Reduces code, increases testing coverage

* refactor(router.py): reduce _common_check_available_deployment function size

make code more maintainable - reduce possible errors

* test(router_code_coverage.py): include batch_utils + pattern matching in enforced 100% code coverage

Improves reliability

* fix(router.py): fix model id match model dump
