Subject: [PATCH] build(dev): replace LocalStack with moto for local S3
 emulation

LocalStack archived its Community edition in March 2026 and moved S3
behind a paid token, so `docker compose up` fails with auth errors for
anyone pulling the current image.

Swap in moto (Apache-2.0), which is built for boto3 and runs the CSV
upload/download flow with an unmodified client -- no path-style or
expect-100-continue workarounds, unlike Adobe S3Mock (Java-SDK-first).
moto has no auto-create, so a one-shot curl container PUTs the upload
bucket once moto is up; this removes the awslocal-based init script.

The app reaches moto at moto:5000 internally; the host port is 5001 to
avoid the macOS AirPlay Receiver on 5000.
