- Add AcademicPeriod model with support for schuljahr/semester/trimester - Extend Event and EventMedia models with optional academic_period_id - Create Alembic migration (8d1df7199cb7) for academic periods system - Add init script for Austrian school year defaults (2024/25-2026/27) - Maintain full backward compatibility for existing events/media - Update program-info.json to version 2025.1.0-alpha.6 Database changes: - New academic_periods table with unique name constraint - Foreign key relationships with proper indexing - Support for multiple period types with single active period This lays the foundation for period-based organization of events and media content, specifically designed for school environments with future extensibility for universities.
