B&W duplicates

Frikkinn 2025 and Hjálpum þeim Iðnó contained paired color/B&W versions of each photo. Even-numbered source files (Mynd-2.jpg, Mynd-4.jpg, ...) were B&W duplicates. These were identified by saturation analysis (ImageMagick HSL colorspace, mean saturation = 0 for grayscale) and removed, keeping only the color versions. 191 B&W images removed in total.

Frontend fix

GraphQL query in next/src/app/myndasafn/[slug]/page.gql.ts needed explicit pagination: { limit: 300 } because Strapi defaults to 100 items per relation. Fixed in PR #30.
