a2nr ac37db5c91 feat(storage): migrasi penyimpanan CSV ke PostgreSQL (SQLAlchemy + Alembic) 
- facade storage: csv_backend + postgres_backend, dipilih via STORAGE_BACKEND
- token disimpan sebagai HMAC-SHA256 digest (TOKEN_PEPPER), tanpa plaintext
- schema alembic 0001: users, access_tokens, lessons, student_progress
- importer CSV idempotent + dry-run + sparse model (not_started tanpa row)
- lesson registry: sync dari home.md (lesson hilang di-deactivate, bukan dihapus)
- routes progress/auth: report & reset via DB, validasi via token hash
- elemes.sh: dbupgrade/dbstatus/dbimport/synclessons/dbverify/dbbackup/dbrestore/dbexport
- podman-compose: service postgres (PG18), tokens_siswa.csv mount :ro
- frontend: api client + progress page; tests kontrak dual-backend + isolasi DB
- load-test: skenario database (locustfile_db.py)
- docs: 01-11 termasuk 11-database-migration.md (arsitektur & operasional)
