fix: add Google Fonts domains to CSP policy

Vuexy loads fonts via webfontloader from fonts.googleapis.com and
fonts.gstatic.com. The previous CSP blocked these, causing a white screen.

- style-src: added https://fonts.googleapis.com
- font-src: added https://fonts.gstatic.com
- Removed frame-ancestors from meta tags (ignored in meta, console warnings)

Updated in all three index.html dev meta tags and both Nginx SPA/portal configs.
