feat(kinkBuilder): use aod::BCs instead of aod::BCsWithTimestamps

The changes in this commit update the usage of the aod::BCsWithTimestamps data
source to the more generic aod::BCs data source. This simplifies the code and
removes the need for the specific BCsWithTimestamps data source, which is no
longer required. The changes ensure that the kinkBuilder functionality
continues to work with the updated data source.
