Subject: [PATCH] Pin local Python services to linux/amd64

The vendored libpdfium.so2 is an x86-64 ELF binary, but on Apple
Silicon Docker runs the containers natively as arm64, so ctypes
cannot load the library. Pin the django/celery services to
linux/amd64 (via the &django anchor) to match the vendored binary
and the production/Lambda environment.
