fix(files_sharing): Hide 'Open locally' action

This patch ensures that the "Open locally" context menu item is not
displayed for files in a share where the "download and sync" permission
has not been granted.

This prevents user confusion, as the action would fail anyway. The fix
adds a permission check before rendering the menu item, and adds a
corresponding unit test to verify this behavior.

Resolves: #54970
