Fix new-capture auto-hide, library capture bar, step delete, and click-capture timing

- New Capture sessions now start paused; the window only tucks away once
  the user clicks "Start recording" in the capture bar instead of hiding
  ~1.2s after starting.
- The capture status bar is shown only in the editor view, not over the
  library.
- Fix openModal/confirmDialog resolving as cancelled when an action button
  is clicked, which made the step "Delete" button (and other modal actions)
  silently no-op.
- Click-triggered captures now use the click-time cursor position for the
  marker and arm the capture cache as soon as recording starts, so the
  first click is captured instantly and accurately placed.
