The nav's feed link already points at the JSON feed, but was using
the feather RSS icon. Adds an SVG recreation of the official JSON
Feed mark (traced from jsonfeed.org's icon) and swaps it in, using a
single dark-green fill throughout so it stays legible against both
the light and dark theme backgrounds.

Removes the RSS and Atom feed routes, controller methods, and views
for both the blog and notes feeds, keeping JSON (and JF2) as the only
supported feed formats. Also serves the JSON feeds with the
spec-required application/feed+json MIME type instead of the generic
application/json.
