fix: Cut/copy/paste path consistency and folder cut support

- pasteEntry: source path now scoped for readText, relative for trash
- cutEntry: removed folder guard — folder cut via api.files.move
- copyEntry: hidden from context menu for folders (not supported)
- Clipboard object now carries isFolder flag
