Deeman c92e5a8e07 ice_stocks: add backfill extractor for historical daily stocks ...

The ICE API at /marketdata/api/reports/293/results stores all historical
daily XLS reports date-descending. Previously the extractor only fetched
the latest. New extract_ice_backfill entry point pages through the API
and downloads all matching 'Daily Warehouse Stocks' reports.

- ice_api.py: add find_all_reports() alongside find_latest_report()
- execute.py: add extract_ice_stocks_backfill(max_pages=3) — default
  covers ~6 months; max_pages=20 fetches ~3 years of history
- pyproject.toml: register extract_ice_backfill entry point

Ran backfill: 131 files, 2025-08-15 → 2026-02-20
