Unified Quote Journal (parts_log) v3

- New unified append-only quote log table parts_log replaces three
  separate log tables (stock_log, partnumber_log_competitors, lot_log)
- Migrations 042-049: extend supplier, create parts_log/import_formats/
  ignore_rules, rework qt_lot_metadata composite PK, add lead_time_weeks
  to pricelist_items, backfill data, migrate ignore rules
- New services: PartsLogBackfillService, ImportFormatService,
  UnifiedImportService; new world pricelist type (all supplier types)
- qt_lot_metadata PK changed to (lot_name, pricelist_type); all queries
  now filter WHERE pricelist_type='estimate'
- Fix pre-existing bug: qt_component_usage_stats column names
  quotes_last30d/quotes_last7d (no underscore) — added explicit gorm tags
- Bible: full table inventory, baseline schema snapshot, updated pricelist/
  data-rules/api/history/architecture docs
