Add HealthChat API and extended profile services (#9)

Expose OpenID tokens and homeserver credentials from the client proxy, and add fork-only services for the HealthChat member directory backend (api.healthchat.ch) plus a service that reads MSC4133 extended profile fields directly from the homeserver. Groundwork for the members tab and the profile screens. Claude-Session: https://claude.ai/code/session_013qdTbAWsZj2quQzEkagXaS
