feat(supervisor): port Python supervisor from padelnomics + workflows.toml

Port padelnomics' schedule-aware Python supervisor to materia:
- src/materia/supervisor.py — croniter scheduling, topological wave
  execution (parallel independent workflows), tag-based git pull + deploy,
  status CLI subcommand
- infra/supervisor/workflows.toml — workflow registry (psd daily, cot
  weekly, prices daily, ice daily, weather daily)
- infra/supervisor/materia-supervisor.service — updated ExecStart to Python
  supervisor, added SUPERVISOR_GIT_PULL=1

Adaptations from padelnomics:
- Uses extract_core.state.open_state_db (not padelnomics_extract.utils)
- uv run sqlmesh -p transform/sqlmesh_materia run
- uv run materia pipeline run export_serving
- web/deploy.sh path (materia's deploy.sh is under web/)
- Removed proxy_mode (not used in materia)

Also: add croniter dependency to src/materia, delete old supervisor.sh.
