Render u-syndication links for /mf2/ better + backfill all previously syndicated links
The u-syndication links are meant to point to the syndicated post, not the place that should syndicate it to (although it's largely because we're abusing Webmentions for syndication purposes).
- For posts with actual permalinks, such as Twitter/Meetup/GitHub/IndieNews, we link to the permalink
- For Bridgy links, we hide them, so they're present to send Webmentions, but don't show anything to the user
- If I don't have a fancy way to display the link, render the hostname
We also want to remove the <details>
tag, as these should be visible
to folks who want to see the posts elsewhere.
This is easier to manage for anything on /mf2/ so we'll just work with that for now.
