Show action status on the stacks list and dashboard, not just detail (0.41.0)

The status banner added in 9d28e12 only rendered on the stack detail
page, but Update is most often clicked from the stacks list — so in
practice the status was invisible. Render it on the stacks list and
dashboard too.

Actions on different stacks run concurrently from the list, so busy
state and status are now keyed by stack id instead of a single value:
previously the first action to finish cleared every row's spinner, and
each new action overwrote the previous one's status. StacksTable takes
an isBusy(id) predicate in place of the single busyId prop.

Also bumps the version so the newly version-tagged CI images (f8bfc91)
actually differ from the running release — self-update compares tags
against APP_VERSION, so shipping without a bump shows no update.
