fix(fetch): handle malformed input without crashing

Changes `raise_exceptions=True` to `raise_exceptions=False` in the fetch server's `Server.run()` call, preventing the server from crashing on malformed JSON-RPC input. This aligns with the SDK's intended default behavior and is consistent with other reference servers.

Fixes #3359
