Subject: [PATCH] style(ci): wrap monthly digest in a colored Slack attachment

Render the digest inside a Slack attachment with a left color bar instead of
bare blocks, matching the PR notifications' look. Uses a neutral light-gray
(#CCCCCC) so the monthly summary reads distinct from the event-colored PR
notifications (green/blue/purple). Both the populated and the "No PRs"
branches get the bar.
