fix: comment out 10 KDE packages with no pkgar — config matches repo

Disabled: kdecoration, kf6-kcmutils, kf6-kdeclarative, kf6-kded6,
kf6-kidletime, kf6-kitemmodels, kf6-kpackage, kf6-kwayland,
kf6-prison, kglobalacceld. All commented as 'blocked: no pkgar
artifact in repo'. Config now matches actual repo artifacts:
26 KDE enabled ≈ 29 KDE pkgar (3 are transitive deps).
