fix(seo): proper 500 handler + safe JSON-LD escaping

Add UseExceptionHandler(/error) so unhandled exceptions return a proper HTML 500 instead of a raw response Googlebot was logging as a server error in Search Console. Replace manual quote-only escaping in blog JSON-LD with a J() helper that uses JsonSerializer so newlines, backslashes, and all other control characters are safely escaped.
