PIL img.resize() on high-resolution photos was exhausting worker RAM,
causing Gunicorn to SIGKILL the worker mid-request (production OOM crash).
Replace the explicit resize() path in both _compress_image_for_pdf() and
_compress_image_for_docx() with:
- Image.draft() — hints the JPEG decoder to decode at a lower resolution
- Image.thumbnail() — in-place resize that avoids allocating a second
full-resolution buffer
This keeps peak memory proportional to the output size instead of the
original file size, preventing the worker from being killed when
processing multi-megapixel service-record photos.
