Fixes #8332

Background

The issue is that when “Run” fails due to invalid inputs (e.g., deleted credentials), no error message is shown in the UI.

Changes 🏗️

• Added toast notification (variant="destructive") for "Run" failures.
• Displays error when the execution request returns an HTTP 400 due to invalid hard-coded input values
