Manage the Slack digest in the admin

New settings area: the webhook lives in the database and is only shown
shortened afterwards, the environment variable stays as a fallback. A switch
decides whether internal entries travel, a button sends the digest right
away, and every run is recorded with period, count, projects, result and
who triggered it.
