v3.1: Add Learning Hub with CMS, quizzes, and 3-role user system

Browse source 
- New Learning Hub under Pediatric menu with content feed, category browsing,
  search, content viewer, and interactive quizzes (MCQ, true/false)
- Quiz system with per-option wrong-answer explanations and general explanations
- Admin CMS for creating/editing categories, content (articles, pearls, quizzes),
  and inline question builder with answer options
- 3-role system: admin (full access), moderator (can manage Learning Hub content),
  user (all clinical features + learning hub read access)
- 5 new database tables: learning_categories, learning_content, learning_questions,
  learning_options, learning_progress
- User progress tracking with score history per quiz
- Moderators see "Content Manager" tab instead of full Admin panel
