dataforth/testdatadb UI: clear, persistent push feedback (toasts)

The push handlers set the button to 'skipped' then immediately ran search(), which
re-rendered the inspector and wiped the text — so a skipped publish flashed and
vanished (looked like nothing happened). Replace with persistent toasts that state the
outcome explicitly: Published / already up-to-date / Push failed / and for a skip,
'<model> isn't renderable yet, so nothing was sent.' Only refresh the row on an actual
publish so the message isn't clobbered. Same for the multi-select Re-push summary.
