feat(dev): add the local profile with recorded third-party answers

Profile "local" points Steam, Twitch/IGDB and speedrun.com to a WireMock
container from compose.yaml (recordings in local/wiremock) and checks
logins against the local Auth.

The IGDB lookups now keep only the ids they asked for: an answer with
another game made tags and release years drop the whole batch.
