* Update connection limit logging to check for changes

Added conditionals to log limit updates only when changes are detected, reducing unnecessary log noise. This applies to both server and client limit updates in the connection logic.

* Fix indentation in server and client limit updates

Adjusted indentation in the `update_limits` methods to ensure values are updated only when changes are detected. This aligns the logic with the condition and avoids unnecessary updates.

* Fix ruff format
