A click on the test Console's Resume button opened window.confirm and the
browser daemon hung: the mouse release, screenshots and the frame tree all
block until the dialog is answered, and ui-browser had no way to answer it.
A click that opens a dialog now returns {dialog:{type,message}}. The new
command `dialog accept|dismiss` answers it and records the type, message
and answer in the receipt. While a dialog is open other commands except
stop refuse (journaled), and no screenshot or URL check is attempted.
A real-Chromium confirm test covers accept, dismiss and the refusals.
A pin corroborates a ledger target only when its binding names its own
campaign and the owner campaign. serveBudget freezes the startup campaign
and ledger paths and retains the ledger with its startup target; a running
service accepts its exactly unchanged startup ledger. Without retained
evidence an owner business/config retarget now refuses as ambiguous.
A valid owner pin and a v2 ledger that disagreed on target still halted
the ledger's binding, so a business-only edit or a foreign ledger could
redirect the stop. The ledger target now needs owner corroboration;
otherwise the owner-verified pin replaces it, or the check refuses.
