refactor: remove unused CMS/JDE repositories and data sources

Remove legacy JDE and CMS direct-access code that is no longer used:
- Delete ICmsDataSource, IJdeDataSource interfaces
- Delete ISearchProcessor, IUpdateProcessor interfaces
- Delete IJdeRepository and ICmsRepository (all partials)
- Delete JdeRepository and CmsRepository implementations
- Delete JdeQueries and CmsQueries
- Delete JdeFileDataSource, JdeOracleDataSource
- Delete CmsFileDataSource, CmsOracleDataSource
- Remove unused methods from LotFinderRepository interfaces
- Delete associated unit tests (CmsRepositoryTests, JdeRepositoryTests)

All data sync now uses ETL pipelines via DataSync project.
