Fix Dockerfile structure for faster rebuilds

Move app file copying from Dockerfile.base to main Dockerfile.
This ensures changes to app.py, client.py, or estimator.py trigger
rebuilds without requiring base image rebuild.

Changes:
- Dockerfile: Add COPY for application files before CMD
- Dockerfile.base: Remove COPY (base image is cached)
