Enhance Kibana visualization to display input record counts for mappings #274
Description
We need to enhance the Kibana dashboards to display the number of input records processed for mappings.
Key requirements:
- Input Record Count: Display the total number of records for the input data associated with each mapping in the relevant Kibana visualization.
- Join Handling: For cases where multiple schemas are joined, display the input record counts separately for each schema involved in the join.
