Greptile Summary

This PR cleanly reverts debug logging and performance instrumentation added in PR #7514. The changes remove temporary diagnostic code that was used to investigate performance issues with the connection listing endpoint.

Key Changes:

• Removed performance timing instrumentation across multiple modules (time.perf_counter() calls and associated logging)
• Removed temporary /connection_legacy endpoint that was added for A/B performance comparison
• Restored simplified transformer lambda in get_connections endpoint
• Removed Redis performance counter utilities (perf_reset_redis_counters, perf_get_redis_counters)
• Cleaned up imports (time, Sequence, unnecessary logger imports)

The revert is complete and restores the codebase to its clean state before the debug changes.

Confidence Score: 5/5

• This PR is safe to merge with no risk
• This is a clean revert of temporary debug code that was explicitly added for diagnostic purposes. All changes remove instrumentation code without affecting application logic. The revert is complete and restores the original functionality.
• No files require special attention
