fix(frontend): new file and folder creation hang, empty folder UX

- Replace circular watchEffects in FileExplorer/Gallery with explicit watchers

  to stop recursive Vue updates when creating items in empty folders.

- Move EmptyFolder rendering inside FileExplorer/Gallery so empty/list swaps

  no longer trigger folder slide transitions.

- Keep EmptyFolder text size consistent across list and gallery views.
