mudler-agentandEttore Di Giacinto f5c4083d7e fix(gallery): tie oci:// gallery caches to the verification policy (#12239)
The unpacked oci:// gallery cache and the last known good copy of the
index were keyed on the gallery URL only. After an operator tightened a
gallery's verification policy (added source_repository, moved not_before
forward), content verified under the older policy, or under none, was
still served for up to an hour from the unpacked cache, and indefinitely
from the last known good copy while fetches failed. A fetch refused by
signature verification also fell back to that last known good copy, so
a refusal became a silent downgrade. Turning strict integrity on did not
stop an unverified cached copy from being served either.

Name both caches by the URL plus a stable hash of the policy. A gallery
without a policy keeps its old URL-only name, so existing caches stay
usable. A fetch refused by the policy, or by strict integrity, is now
reported and never answered with a cached copy; a network failure still
falls back, but only to a copy verified under the current policy. The
strict integrity check runs before the cache is read.
