Fix Bluesky author icon and regenerate stale assets

The author-links partial mapped `bluesky` to `fas fa-cloud`, rendering a
generic cloud instead of the Bluesky logo. FontAwesome 6.7 ships a real
`bluesky` brand glyph, so switch to `fab fa-bluesky` and regenerate the
subset (also picks up pre-existing drift: fa-calendar-times + Tailwind).

Also regenerate the purged CSS and FA subset at deploy time so the live
site is never stale even if a PR merges (or the build guard is overridden)
without the rebuilt assets committed.
