feat(imageresizer): extend context menu to all supported formats

Fixes #1929 The 'Resize pictures' context menu option now appears for all image formats that Image Resizer can process, not just common formats. Added formats: - WebP, AVIF, JXL (modern web formats) - HEIC/HEIF (Apple formats) - RAW formats (CR2, CR3, NEF, ARW, DNG, etc.) - HDR formats (HDR, EXR) - Legacy formats (TGA, PCX, PBM, etc.)
