Misaka_Company 21089e8b40 perf(import): bypass intermediate Excel file in extraction pipeline ...

Replace the Extract → Write Excel → Read Excel → Import DB flow with
direct record-to-database persistence. The extractor now builds
MaterialPlanRecord[] from parsed orders and imports them without the
round-trip through a merged Excel file.

Key changes:
- Add importFromRecords() to DataImportService for record-based import
- Add SQL Server OPENJSON batch insert and atomic replace operations
  in DiscreteMaterialPlanDAO for efficient bulk writes
- Extract common import logic into private importRecords() method
- Configure explicit request/connection timeouts for SQL Server
- Add unit tests for direct record import path
