F-LAB-28: permitir modificar tomas configuradas (solo las no firmadas)

- PHP: restaura auto-apply de _tomas_config para mostrar tomas correctas en recarga
- Badge: agrega botón 'Modificar' cuando el examen ya está configurado
- Panel: en modo modificar pre-marca las tomas guardadas y deshabilita
  las ya firmadas (con ícono ✓ y opacity reducida)
