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.
