fix: database initialization on sqlite and i18n logic

- Nuevo modelo StudentEnrollment (tabla student_enrollments)
  con inscripcion unica por alumno/comision, estado y notas

- Migracion automatica en init_db.py (CREATE TABLE IF NOT EXISTS)

- Rutas /admin/commissions/ para Bedelia y Admin:
  listado con filtros, detalle, asignar docente,
  inscribir/dar de baja alumnos, cambiar estado

- Blueprint my_subjects_bp en /mis-materias:
  Docente ve solo sus comisiones asignadas
  Alumno ve solo sus inscripciones activas
  Admin/Bedelia ven todo

- Templates: admin/commissions/list.html, detail.html
            my_subjects/list.html, detail.html

- Navbar actualizado por rol:
  Docente y Alumno: 'Mis Materias'
  Bedelia y Admin: 'Gestion de Comisiones'
