Attribution du fork, README, logo UI et workflow GHCR

- NOTICE.md : Loki est un fork d'AJEAN (nathaninline, MIT), liste des
  modifications ; LICENSE amont conservée à l'identique.
- README réécrit : bandeau fork, architecture conteneur, démarrage Docker,
  procédure Unraid (plugin Nvidia Driver), différences avec l'amont.
- UI : le logo pixel-art épelle désormais LOKI (il épelait encore AJEAN),
  infobulle d'attribution sur la marque ; index.html régénéré.
- Workflow GHCR : libération d'espace disque du runner (l'étape CUDA devel
  ne tient pas dans les ~14 Go libres), build-args CUDA_ARCHS/LOKI_VERSION,
  cache GHA en mode min (plafond 10 Go).
