Normalize extracted theme fonts before loading them

Ensure fonts are properly trimmed and stripped of quotes to maintain consistency and avoid potential loading issues.

The default fonts defined by MUI e.g., are set as "\"Roboto\", \"Helvetica\", \"Arial\", sans-serif" which lead to an invalid font request.

Fixes #1012
