bug: Update entities briefly show containers as upgradable after upgrade

[gensyn]

SSH Docker version
1.2.2

Home Assistant version
2026.7.1

Issue / Experienced behavior
After upgrading a container through its update entity, the update entity reverts to the state of upgradable while the container is being reloaded and only then recognizes it as up-to-date.

Expected behavior
No update entity after upgrading containers or a state like "fetching", "loading" etc.
