Subject: [PATCH] Fix po-email-processor bundling for arm64 target (#34)

po-email-processor has been down since 2026-05-12: the bundling
command installed wheels for the build host's architecture, so CD
deploys from amd64 runners shipped x86_64 pydantic_core into an
ARM_64 function, crashing every INIT with Runtime.ImportModuleError.

Pin the pip platform to manylinux2014_aarch64 with --only-binary,
matching the pattern wo_stack already uses.

Verified live: deployed from branch, manual invoke OK; 920 emails
from the outage window backfilled via scripts/reprocess logic.
