refactor(datasync): remove deprecated SyncMode and SyncModeConfig

- 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.
