Blocked connector sign-ins show a shorter, fixed message

A connector links Claude Code to an outside service. When signing in to one is blocked, the message used to start with a shared opening followed by more detail. It is now fixed text that names the connector and says it was checked against your organization's connector settings, so the sign-in was stopped. The detail that used to follow is gone.

The message shown when a cyber verification check refuses a request has also changed. Its text now depends on the tier or reason, falls back to a plain message, and no longer includes advice to use /feedback or a link to a portal.
