Adam Moussa e66062c934 Align PO schema with enriched records and improve extraction prompt ... Replaces extraction prompt with domain-specific rules: trade classification taxonomy (23 categories), site_code skip list, zip padding, revision email type, and structured extraction for fiscal_year, trade, and coupa_category. Handler changes: - New "revision" email type overwrites existing PO via put_item - enrich_parsed() adds top-level state, ship_to_raw, data_source - pad_zip() zero-pads short zip codes (e.g., "7001" → "07001") - Removed invoice_total/invoice_count (Payee Central only) Web UI: added revision badge, new detail fields (site code, state, trade, fiscal year, coupa category, data source), line item table now shows Qty/Unit/Price columns, list view shows Site and Trade. CDK: fixed StreamViewType to match deployed table (NEW_IMAGE). README: documented PO record schema and revision flow.		2026-05-01 19:53:26 -04:00
