Feed form: relays and an every-post firehose; its Back works; a stronger new-post tint

- The new/edit feed form gets a Relays field (read this feed from these
  relays only) and "Every post on these relays", which saves a firehose
  feed (optionally curated) named after its relay and hides the people,
  packs and topics it doesn't need. It used to take a hand-typed
  /feed/all?r= link.
- The form's Back did nothing visible: opening it made no history entry,
  so Back went to the page behind the feed and left the form up. The
  editor (and the gear page's Spending/Savings view) are now part of the
  navigation state.
- New-post tint 9% -> 16% green in light mode; dark mode unchanged.
- tools/feed-editor-relays-test.js.
