Bridge Brokerage and Market Data APIs

When ingesting brokerage data (e.g., Fidelity CSV) and fetching live prices from market APIs (e.g., Yahoo Finance), ticker symbols often differ. Create a centralized TICKER_MAP dict to alias brokerage symbols to API symbols (e.g., BRKB → BRK-B). Also extend API queries with a longer period window (e.g., 5d instead of 1d) to handle weekends/holidays returning empty data. Apply the mapping at the ingest layer before price-fetch calls.
