Drops the cozystack.http-cache-application PackageSource and its entry
in the naas bundle.
No migration accompanies this. Platform Package objects carry
helm.sh/resource-policy: keep, so an existing cluster keeps its
http-cache Package and its http-cache-rd HelmRelease, and with them the
ApplicationDefinition that makes the kind resolvable. Instances that are
already deployed therefore keep running and stay addressable; the
platform simply stops delivering and updating the application. Removing
those objects would be the more invasive choice, not the safer one,
because there is no successor in the catalog to migrate an instance onto.
The httpcaches grant in cozy:tenant:admin:base stays for now. It is the
only rule in the tenant admin chain that can delete an instance, and no
tenant role carries any verb on helm.toolkit.fluxcd.io, so without it
the owner of a surviving HTTPCache could not remove it at all.
