deps: adopt russh 0.63.1 and uuid 1.25.0

russh 0.63 changed the check_server_key callback to take
&PublicKeyOrCertificate; resolve it to a PublicKey via .public_key() in
both the tunnel and probe handlers, and widen the russh constraint to
0.63. Closes the retargeted dependabot PRs #204 (uuid) and #205 (russh).
