Make the reply footer a snippet, not a rule

Routing garden notes and /now/ through post.html put the invitation to reply on
them because a directory said so, which is the wrong thing to be automatic — it
is a choice about each page, and I had made it site-wide to chase parity with
the live site.

Those two rules are gone; blog posts keep it. The wording now lives in
templates/reply.html rather than inside post.html, so it can be edited or
emptied without touching how a post is built, and editing it re-renders the 170
pages that include it and nothing else.

Any page opts in for itself with `#+TEMPLATE: post.html`; any post opts out with
`#+TEMPLATE: base.html`.
