Merge origin/dev (Feature 20 scheduler) into Feature 21 Home dashboard

Keep both the scheduler registrations and the Home service wiring in
cmd/server, pass the scheduler wake function to plan.NewService in the
Home and server tests, and document that boot catch-up processes every
unclaimed fire time within 24 hours, oldest first (F20-02).
