Subject: [PATCH] Standardize: Convert final 4 queries to prepared statements -
 ALL COMPLETE
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Converted final queries in:
- bush_mechanics.php - Course query
- rescue_recovery.php - Course query
- admin_members.php - Membership applications query

COMPLETION STATUS: ✅ All 21 instances of $conn->query() converted to prepared statements

Files updated: 14
  Functions.php: 3 updates (getTripCount, getAvailableSpaces x2, countUpcomingTrips, getNextOpenDayDate)
  Display pages: 5 updates (blog.php, course_details.php, driver_training.php, events.php, index.php)
  Data pages: 2 updates (campsites.php, admin_members.php)
  AJAX handlers: 2 updates (fetch_users.php, get_campsites.php)
  Course pages: 3 updates (bush_mechanics.php, rescue_recovery.php)

Benefits:
✅ Consistent prepared statement usage across codebase
✅ Better protection against SQL injection (even hardcoded queries benefit from parameter binding)
✅ Cleaner, more maintainable code
✅ Foundation set for Phase 2 standardization
