🔧 Bug Fixes & Stability

1. Clear destination S3 Parquet path handling -
   Fixed S3 Parquet path trimming in clear destination operations to properly handle whitespace in provided paths.

2. Increase Iceberg commit timeout -
   Extended Iceberg commit and write request timeout from 300s to 3600s to improve reliability for large data batches.

3. Clear destination stream cleanup fix -
   Corrected destination database checks so the streams are correctly detected and dropped during clear destination, ensuring complete cleanup.

   Updated balancer to assign consumer readers only to partitions with available data, preventing idle consumers from blocking on empty partitions and eliminating indefinite fetch waits until context cancellation.
