[Story]: Rework Warning Messages

[lukehinds]

Description

Currently CodeGate provides warning text upon detection of leaked secrets, tokens or PII. This was sutiable for coding assistants, but not so with other systems (especially agents). Instead this data should be recorded and retrievable via API, where it can be access on a per need basis. In time we may want this to have a trigger capability allowing it to be subscribed too , with perhaps a webhook / event bus.
