Hub: accounts, IMVU linking by tagline, proxy sign-in, presence, console

People sign up on the website and link IMVU accounts by putting a code in the account's tagline, which the
hub reads from IMVU's public API (the most recent proof wins; link caps per person). IMVU's age verification
or Access Pass make an account adult. T5DE's proxy signs in with a device code and keeps a WebSocket open,
reporting the IMVU account in use and the community products it wears; /online shows those who opted in.
Moderators get a console: who's online, people, link caps, bans, roles, and the audit log. Tests run the
website and API against an embedded Postgres and a fake IMVU API.
