Add robust dev fetch logging

Improve ApiDevTools to log fetch errors with stack traces during development, fix UUID generation fallback for environments lacking crypto.randomUUID, and ensure errors are surfaced in the browser console for easier debugging. Includes fallback generateUUID and preserved patching with proper catch blocks.
