/**
 * TRU-76: DHL daily goal for Taulov/Taastrup was not posting to Slack because
 * GoalsProgressAlertsCron only consulted the per-department `slack_webhook`
 * field. For "internal" departments (Taulov/Taastrup are configured as
 * internal) those per-department webhooks are intentionally empty — the
 * dedicated internal goal progress webhook is the right destination.
 *
 * These tests pin the new dispatch behavior:
 *   1. The cron reads internal_department_ids from the Slack config.
 *   2. When ALL goal departments are internal AND the dedicated
 *      internal_department_goal_progress_webhook_url is configured, the cron
 *      posts to that webhook (not the per-department one).
 *   3. When the dedicated webhook is empty, the cron logs a diagnostic
 *      message and falls back to the per-department webhook loop.
 *   4. When the goal includes any non-internal department, the cron skips
 *      the dedicated webhook entirely and uses the per-department loop.
