Hermes Reyna Bot 869c97d7b9 ImmichElias: dynamic display sizing for 3.5 inch (480x320) 
- detect display via lv_display_get_horizontal/vertical_resolution
- img target = full width x (disp_h - overhead) for any screen
- fetch_png_from_proxy now takes req_w/h params (was hardcoded 320x240)
- proxy 8106 already handles w/h: tested 320x240 81KB, 480x320 141KB, 320x480 176KB, 800x480 297KB
- THUMB_BUF_SIZE 200KB->512KB for larger PNGs
- Works on yellow 320x240 and new 3.5 inch 480x320 both
