fix: color de fonde dels sliders de 050505 a 000000

- Mapa té un JD8_Surface fondo propi que s'allibera al destructor: una
  còpia accidental provocaria double-free. Ara els 4 copy/move ops estan
  = delete.
- ModuleGame ja era no-copiable implícitament per tindre unique_ptr
  members, però els = delete expliciten la intenció i protegeixen
  davant refactors futurs que afegeixquen tipus copiables.

Fi de la modernització RAII per fases (1–6).
