StockMarketAPI: List Sectors. List sectors with the count of active companies in each. Sectors are the canonical GICS names (e.g. ``Information Technology``, ``Health Care``). ``/sectors/{sector}/stats`` also accepts provider-style or aliased inputs (``Technology``, ``Healthcare``, ``Financial Services``) — they canonicalize to the stored name — but these are the exact strings we store.
