feat: show the meta.sr.ht audit log

auditLog existed in the API but was never called, so the record of what has
happened to your account — logins, key changes, the addresses they came from —
was web-only.

Sits under the tokens in Profile and loads on demand for the same reason they
do: an audit log is something you go looking for, not something worth a request
on every profile view. One page, newest first; the archive stays on meta.sr.ht.

Its errors are kept separate from the shared `error` so a failed audit fetch
cannot bury a profile save failure, and vice versa.
