1.1.5: settings/media folder details + empty-click deselects everything

- Settings → Media tab now shows per-folder image/audio counts, skipped
  subfolders, skipped files, and a rescan button. listClipart hard-skips
  subdirectories and unsupported file extensions, returning a skip
  report the panel renders.
- Empty-click anywhere — chrome, bare stage, empty timeline tracks —
  clears the full selection (layers, clip instances, keyframes) via a
  shared useDeselectAll helper. shouldChromeClickDeselect() splits
  exclusions into interactive elements, overlays, editing panels and
  timeline selection elements so empty timeline space deselects too.
