Ignore api dir and update bundle output path

Add 'api' to apps/studio/.gitignore and update apps/studio/scripts/bundle-api.mjs to write the bundled server to api/index.js (previously dist/api/index.js). Also update the console log to reflect the new output path. This keeps generated API bundle files out of source control and aligns the bundle script with the new output location.
