Minimal single-column layout for direct /finger/<user> links

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.
