fix(iis): exclude static files from URL rewrite

Updated the URL rewrite rule in `web.config` to ensure that certain static files,
including `manifest.json`, `.ico`, and image files, are not rewritten to `/`. This
change prevents the unintentional rewrite of these files, which can cause them to
not be served correctly.

Additionally, verified and ensured correct MIME types for static content, including
`application/json` for JSON files.

This should resolve issues with static resources not loading properly on IIS.
