refactor: remove unused classes and consolidate ViewModels in Core

Remove 9 unused types from Core (duplicate extension classes, TableSpec, ColumnSpec, LotLocation), move ComponentLotViewModel and OperatorViewModel from Client to Core, and refactor DataSync.Dev to use pipeline-based configuration. Fix Login.razor to use UserInfoDto directly.
