improve delete performance for clickhouse (#132)
### TL;DR
Improved the deletion logic in case of reorgs in ClickHouse by implementing partition-aware deletes and disabling lightweight delete synchronization.
### What changed?
- Added `lightweight_deletes_sync` setting (value 0) to ClickHouse configuration. This will make the deletes async, so processing does not need to wait for it to finish
- Split generic `deleteBatch` function into specific delete functions for blocks, logs, transactions, and traces, which will improve performance due to having all of the order by keys defined
- Implemented two-step deletion process:
1. Query for existing records that need deletion
2. Execute targeted deletes using partition values and primary keys
- Added proper error handling and batch processing for deletions
### Why make this change?
The previous deletion method was inefficient and could cause performance issues in ClickHouse.File tree
