Align ConfigManager with DataSync's per-file pipeline format (pipeline.*.json)
by reusing EtlPipelineConfig types directly, eliminating duplicate models and
simplifying the codebase. Removes ~3200 lines of obsolete code.
Add ConfigurationValidationRunner with IConfigurationValidator interface for
validating required settings at startup. Includes SecureStore and LDAP validators.
Expand ConfigManager with pipeline editing UI, dialogs, and step editors.
Update documentation with config validation guidance.
- Delete SyncMode.cs enum file
- Remove SyncModes property from PipelineConfig
- Remove SyncModeConfig and DestinationOverride records
- Remove WithMode(SyncMode) from IEtlPipelineBuilder
- Remove BuildWithSyncModes() and related methods from EtlPipelineFactory
- Remove syncModes sections from all pipelines in pipelines.json
- Update tests to use schedules-only configuration
All pipelines now require 'schedules' format (mass/daily/hourly).
WithUpdateType(UpdateTypes) is the only way to set update type.
Update TableSyncOperation to pass UpdateTypes directly to the pipeline
builder using WithUpdateType() instead of mapping to SyncMode and calling
the deprecated WithMode() method. This enables proper schedule-based
configuration handling where Daily and Hourly have distinct behaviors.
- Remove SyncMode mapping logic from ExecuteSyncCoreAsync
- Call WithUpdateType(task.UpdateType) directly
- Update log message to reflect UpdateType instead of SyncMode
- Add TableSyncOperationTests verifying WithUpdateType is called correctly
