fix(jwt-auth): soft-fail unresolvable x-litellm-team-id for admins

Previously, an admin JWT sending a stale/typo'd/missing x-litellm-team-id
on an LLM API route received a hard 404 from get_team_object, blocking the
request. Restore pre-PR admin behavior: if the header can't be resolved,
skip team attribution and proceed with admin access, logging a warning
with the header value and route so the misconfigured caller is diagnosable.
