refactor(openflare): unify protocol API responses to Wavelet format

Migrate Agent/Relay/Tunnel handlers from compat {success,message,data}
to response.OK and response.Abort* with real HTTP status codes. Remove
the compat package and update openflare-agent, openflare-relay, and
openflared clients to parse {error_msg,data}.
