Additional description

Fix 9 bugs where the client produces wrong results without raising errors:

• Cluster transaction validation accepts all command types due to Python or operator misuse (if x == A or B: is always True)
• Compare exchange double-create in same session goes undetected (same or pattern)
• Batch patch status always treated as CREATED/PATCHED (same or pattern)
• WaitFor replication/index builder settings written to wrong fields (copy-paste from adjacent builders)
• Batch results silently dropped after time series operations (break instead of continue)
• update_session_after_save_changes was a no-op with a TODO comment (cluster TX index not propagated)
