CSS: m.facebook.com

This script adjusts UI of m.facebook.com to enable text copying on mobile browsers:
- the link, which covers the whole message text, is removed (not relevant under the new UI since July 2023)
- cursor is made normal
- text selection is allowed (under the new UI since July 2023 the text selection is impossible for posts with "...see more" link; trying to fix it)

Please try another script for m.facebook.com, which removes useless Facebook panels in mobile browsers: https://gf.zukizuki.org/en/scripts/419357
