feat(datasync): implement GetRecentUpdatesAsync and GetLastRunsAsync

- GetRecentUpdatesAsync: Returns last N DataUpdate records for a table,
  optionally filtered by UpdateType, ordered by StartDt descending
- GetLastRunsAsync: Returns the most recent run (successful or not) for
  each UpdateType for a given table using a CTE with ROW_NUMBER
