* fix(proxy): match passthrough registry routes bare-to-bare with SERVER_ROOT_PATH
After #28547, get_request_route strips the deployment prefix while registry
lookup still re-inflated stored paths via SERVER_ROOT_PATH, causing 404s
under paths like /llmproxy/ml. Compare normalized bare routes in both
is_registered_pass_through_route and get_registered_pass_through_route.

and JWT tests must mock litellm.proxy.utils where normalization reads it.
