Pull request overview

Optimizes the goal_reminder_email management command to reduce memory usage and pre-filter goals at the database level. An Exists subquery now eliminates CourseGoal rows whose users have no eligible active enrollment, the queryset is streamed via iterator() instead of being fully materialized, and len() calls are replaced with count(). The per-goal timezone check is moved to the start of handle_goal so the cheapest filter runs first, and Site.objects.get_current() is hoisted out of the loop.

Changes:

• Push enrollment eligibility filtering into a DB-level Exists subquery and stream results with iterator(chunk_size=500) + count() instead of len().
• Move the timezone window check to the top of handle_goal to short-circuit early.
• Hoist Site.objects.get_current() out of the per-goal loop.
