WSL: webviews are broken (scripts/images fail to load)

The latest update now fails to invoke lambda functions. Previously I was able to click the `invoke` button and have the results returned but now clicking the button produces no output.

The logs report that it cannot find the SAM CLI but otherwise contain no error. I can invoke the function from the terminal using the cli. (I'm assuming the credentials etc are properly configured, as I can list the functions in the explorer.)

Reproduce the failure in WSL by opening the affected webview and using the invoke button; compare its logs with a terminal SAM CLI invocation. Trace the webview's script and image loading alongside the Lambda invocation path, then verify that assets load and invocation results appear without the missing-SAM-CLI error.
