Webhook URL character limit increase

Business problem

The URL field for webhooks currently has a character limit of 255, which causes longer URLs—such as those generated by Power Automate—to be truncated upon saving. Because there is no validation warning, the URL is saved in an incomplete state (often missing critical parameters like signatures), leading to silent webhook failures.

Wished result

The character limit for the webhook URL field should be increased to accommodate long integration links. Additionally, input validation should be implemented to prevent saving if the URL exceeds the maximum allowed length, ensuring the webhook remains functional.
