fix(image_loader): match prototypes with implementations

The image loader header still declared old load_gz_img/load_zstd_img signatures and a non-const load_img path argument, while the implementations already take an explicit destination buffer and const input path.

Update the header before reusing load_img from flash.c, so new callers include the actual interface instead of stale prototypes.
