Re-enable Heart routine crons; heart-health moves to 05:00 UTC

Lifts the 2026-07-06 org-wide cron pause for Heart. heart-health runs daily at
05:00 UTC (was 06:00) so its verdict is fresh when PyAutoMind's morning_health
message reads it at 06:00; workspace-validation and url-check return to their
Monday slots.

Part of #39.
