feat(db): v4 migration + shared types for specialist auto-assignment

Adds auto_assign_specialist + working_hours to businesses, and specialties + working_hours + efficiency_score to employees, with idempotent migrateV3ToV4 (backfills default Lun-Vie 09:00-20:00 working hours). Updates Business/Employee types and adds WorkingHoursMap.
