Subject: [PATCH] ReadMeABook: start the scheduler with the service (#17950)

Only GET /api/init creates the scheduled jobs and starts the scheduler; upstream's image calls it after every start, the LXC never did (#17945). An ExecStartPost hook now waits for the app and Redis like app-start.sh, and update adds it to existing installs.
