"""
Migration: Add data_collection_mode column to projects table.
Values:
"remote" — units have modems; data pulled via FTP/scheduler automatically
"manual" — no modem; SD cards retrieved daily and uploaded by hand
All existing projects are backfilled to "manual" (safe conservative default).
Run once inside the Docker container:
docker exec terra-view python3 backend/migrate_add_project_data_collection_mode.py
