perf: aggressive webp re-compression + max-width 1920 resize

- recompress every webp at q=70-82 depending on size band
- resize anything wider than 1920px to 1920 max
- convert remaining png/jpg holdouts (mine, thermal, dex3-1 etc) to webp
- restore apple-touch-icon.png (iOS requires png)
- 86 files recompressed, saved 4.36 MB
- public/ images: 11.7 MB -> 6.69 MB (-43%)
- total trajectory: 23.3 MB -> 6.69 MB (-71%)
