[PATCH datacenter-manager v2 0/2] fix an issue with cached subscription info

[Shannon Sterz <s.sterz@proxmox.com>]

and slightly improve the caching mechanism. the second patch here is
optional, it's just something i noticed while debugging.

Changelog
---------

changes since v1 (thanks @ Fabian Grünbichler):
- https://lore.proxmox.com/pdm-devel/20260603115442.361184-1-s.sterz@proxmox.com/)
* added a helper function that guarantees freshly fetched info that
  never touched the cache. the last version had a slight chance of a
  race occurring and us again getting cached, incomplete information.
* improved logging.

Shannon Sterz (2):
  server: subscription: always get fresh subscription info on update
  server: cache: short-circuit on special max age value 0
