Fix image fields to open the real media library picker (v2.1.1)

wp_enqueue_media() was never called on the Settings page, so wp.media
was undefined client-side and every image field (Logo, Dark mode logo,
Login logo, Admin favicon) silently fell back to a plain URL prompt
instead of the WordPress media library. Also relabeled the picker
button ("Choose from media library" instead of "{label} url") so it
reads as a picker, not a URL field.
