fetch-bank-data

Use when the user says "fetch bank data", "pull from bank", "fetch hapoalim", "fetch cal", "fetch credit card", "pull from cal", or any morning-equivalent. Pulls fresh transactions + balances from Bank Hapoalim and Cal via `israeli-bank-scrapers`, reasons about each source's data to attach observation tags + a sidecar notes file, and drops paired files into Drive `dump/` for the next `sync-finance-data` run to ingest.
