Replaces the follow-the-task navigation from the previous commit —
carrying the user to the tasks page and back was feedback by relocation.
This is feedback where the click happened: the button becomes
"Updating…" with a spinner and stays disabled until the task reaches a
terminal state, then the data refetches and the row repaints with the
result. Update, Update all / selected, the stepped Upgrade and Roll back
all get it (verbs keep their own labels: Upgrading…, Rolling back…).
Two paths keep the face honest. A DOM patch flips the buttons the moment
the click lands — no waiting for a render pass — stashing the original
face on the element so a failed dispatch can restore it. And every
renderer now builds these buttons through one busy-aware helper, so a
repaint landing MID-task (the auto-refresh poll, a filter change)
reconstructs the spinner instead of silently re-enabling the button.
Sibling actions are held while a task runs: Roll back on an app that is
mid-update is disabled — without a spinner, which marks the action that
is running, not the ones waiting on it. Entry points also guard on the
inflight set, so a keyboard-triggered duplicate is inert.
Correlation is by task id (routeAction resolves to the created task), so
another task finishing cannot end this button's busy state early. Only
completed/failed/cancelled end it; listeners are removed on the first
terminal event, with a 30-minute timeout so a task that never reports
terminal cannot pin a spinner forever. cursor is "progress", not
"not-allowed" — the work is happening, the button is not refusing.
