refactor: rename materia → beanflows throughout codebase

- Rename src/materia/ → src/beanflows/ (Python package)
- Rename transform/sqlmesh_materia/ → transform/sqlmesh_beanflows/
- Rename infra/supervisor/materia-supervisor.service → beanflows-supervisor.service
- Rename infra/backup/materia-backup.{service,timer} → beanflows-backup.{service,timer}
- Update all path strings: /opt/materia → /opt/beanflows, /data/materia → /data/beanflows
- Update pyproject.toml: project name, CLI entrypoint, workspace source key
- Update all internal imports from materia.* → beanflows.*
- Update infra scripts: REPO_DIR, service names, systemctl references
- Fix docker-compose.prod.yml: /data/materia → /data/beanflows (bind mount path)

Intentionally left unchanged: Pulumi stack name (materia-infrastructure) and
Hetzner resource names ("materia-key", "managed_by: materia") — these reference
live cloud infrastructure and require separate cloud-side renames.
