The foundation modules claim a mesh-scoped seat named after their server

postgres claims mesh-store, lavinmq claims mesh-broker, and the controller's seat is
renamed the-controller -> mesh-controller so all three follow one convention. The resolver
refuses a second holder mesh-wide, so an adopted foundation module assigned to a second node
is refused rather than silently raising a second server. Closes hq issue 056 (ADR 0079).
