test(dawarich): pin the movement block, the channels and the mocks; document the connection

Covers the day section, the model projection without the travel country and
the two correlation channels; the backup and correlation mocks learn the new
delegate. Adds the operator page for DAWARICH_PRIVATE_ORIGINS and regenerates
the API contract.
