Lemur: Incomplete fix for GHSA-v2wp-frmc-5q3v -- ACME authority update endpoint allows non-admin to replace `acme_url` with internal IP, bypassing allowlist

SummaryThe fix for GHSA-v2wp-frmc-5q3v added validateacmeurl to reject acmeurl values not in ACMEDIRECTORYHOSTALLOWLIST, but the validation is only called at authority creation time POST. The authority update endpoint PUT /api/1/authorities/ accepts and stores arbitrary options -- including a...
