refactor(log): migra els subsistemes restants i elimina iostream

Acaba la migració dels std::cout/cerr a Log::*:

- core/locale, core/ui/ui_config, core/rendering/{screen,text,gif,
  surface, sprite/animated_sprite, sdl3gpu/*}.
- game/{options, debug_config, editor/editor_config, levels/level_manager,
  map/{map,tilemap,paint_layer}, entities/entity_manager_loadlevel}.

Severitats coherents: warns per a configs absents amb fallback,
errors per a YAML malformat o E/S fallida, infos per a estats.

Resultat:
- 0 occurrences de std::cout/std::cerr a source/.
- Cap #include <iostream> orfà (eliminat de surface.cpp).
- Output funcional idèntic al històric; AEE_LOG filtra (ex.
  `AEE_LOG=warn` només mostra warnings, `AEE_LOG=*:warn,Tag:info`
  combina globals i overrides).
