Enhance Kibana visualization to display input record counts for mappings

[dogukan10]

We need to enhance the Kibana dashboards to display the number of input records processed for mappings.

Key requirements:

1. Input Record Count: Display the total number of records for the input data associated with each mapping in the relevant Kibana visualization.
2. Join Handling: For cases where multiple schemas are joined, display the input record counts separately for each schema involved in the join.
