fix(img): fix WebP Content-Type bug and seed 232 missing FileStorage records

- img.ts: replace hardcoded 'image/jpeg' Content-Type with dynamic MIME_MAP
  lookup per file extension — WebP files now served with correct 'image/webp'
  header so browsers can decode them
- img.ts: skip sharp resize when no size param (serve original buffer directly)
- Adds migration 20260423072135 to add stok and umkmId columns to PasarDesa
- FileStorage DB now has all 232 MinIO images seeded (was 80, missing 152)
- All domain records (Berita 18/18, GalleryFoto 3/3, PasarDesa 4/4, etc.)
  now have imageId properly linked after full re-seed
