Add timetable scheduler Phases 1 + 2 to school-service

Phase 1 — Stammdaten (7 tables): tt_class, tt_period, tt_room, tt_subject, tt_teacher, tt_curriculum, tt_assignment with CRUD endpoints. Phase 2 — Constraints (15 typed tables): Teacher (6): unavailable_day, unavailable_window, max_hours_day, max_hours_week, excluded_subject, excluded_room Subject (5): min_day_gap, max_consecutive, contiguous_when_repeated, preferred_period, double_lesson Class (2): max_hours_day, no_gaps Room (2): requires_type, unavailable Each constraint row carries is_hard / weight / active / note / created_by_user_id; ownership enforced via WHERE EXISTS against the parent tt_teacher/tt_class/tt_subject/tt_room row.
