Unify the interactive /finger page on the same results-first layout
introduced for direct /finger/<user> links: drop the two-column view
(About Finger panel, success banner, timestamp, back-to-home button)
and the now-unused direct flag.
Direct links now render a results-first single-column view: drop the
About Finger panel, success banner, timestamp and back-to-home button,
and replace the lookup card with a small inline form next to the heading.
The interactive /finger page keeps its original two-column layout.
base.html referenced url_for('api_hello'), but that endpoint is now
api_info (/api/info). Since every page extends base.html, the dead
reference raised werkzeug BuildError and returned HTTP 500 site-wide --
including /finger/<user>, which federated Mastodon instances fetch for
link previews. The 500s also defeated nginx's 200-only cache, so every
fetch re-ran the finger subprocess against the daemon on mammut.
