fix(docs): delete the legacy API docs page and drop a redirect hop

/api?old=1 still rendered the whole pre-Mintlify docs page: 200, 81KB,
its own title, no noindex, and a canonical pointing at /api, which is
itself a 301. So an orphaned copy of the docs stayed indexable and
competed with the real ones for the same queries, and the page said in
its own body that the docs had moved.

The escape hatch and its template are gone, and the docs redirects now
point at spoo.me/docs directly. docs.spoo.me still resolves but 301s
there, so every redirect through it was costing a second hop.
