fix(capture): + button opens the capture sheet again in triage and tasks

Hold-to-record opened the sheet on pointerup; the click the browser sends
right after landed on the new sheet's backdrop and closed it at once.
Lists and notes have no such backdrop and kept working. A short tap now
opens on the click itself (as before), and after a hold that click is
ignored. Tests send the real pointerup + click sequence. Version 0.5.1.
