Fix MultiSelect component styles and CSP error (#3841)

* Update Web styles and CSP to support MultiSelect component

- Include the MultiSelect module in the CL barrel file of exports
- Import the MultiSelect scss into the Web styles.scss
- Add the necessary sha256 hash to webpack CSP policy to support ngSelect inline styles

* Undo removal of 127.0.0.1 from webpack CSP
