[#9485] Fixed the appliance Updates tab showing a blocking "Update all in progress" panel — for a run you never started — after upgrading. The tab now detects a finished or a stuck/orphaned update on first load and shows a dismissible panel instead of locking: a completed update reads as done, and a stalled one shows an "Unfinished Update all found" notice (naming when progress last advanced) with a Cancel stuck run action.
[#9486] On the Updates tab, the Channel buttons and the Release set dropdown are now the same height and no longer shift the layout when you switch channels. A new downgrade safeguard also warns, with a two-step confirm, when a selected update would move a component to an older version — since a downgrade can't be automatically assessed or rolled back.
[#9484] On the Docker tab, the Restart/Disable buttons on the service cards (InfluxDB, Grafana, PostgreSQL, and the others) now line up along the bottom of each card instead of floating at different heights.
