bug: Dockerfile copies nonexistent seed.py and documents obsolete SQLite runtime

[Panacota96]

Summary

The container image definition still assumes a seed.py file and a SQLite runtime, but the repo uses DynamoDB and no seed.py exists at the root.

Evidence

• File: Dockerfile:14
• COPY config.py run.py seed.py ./ references seed.py, which is absent.
• Dockerfile:17-26 creates /data and sets DATABASE_URL=sqlite:////data/app.db, which no longer matches the application architecture.

Impact

• Docker builds are misleading or broken depending on context.
• Local developer guidance diverges from the actual runtime model.

Expected outcome

Align the Docker image with the current Flask+DynamoDB architecture and remove stale SQLite assumptions.
