Test User f8ea417799 fix(GRO-642): sanitize logo MIME type to prevent XSS in data URL rendering
Add ALLOWED_LOGO_TYPES allowlist check before constructing data URL from
user-controlled logoBase64 and logoMimeType fields. Only MIME types that
the API explicitly accepts (image/png, image/jpeg, image/gif, image/webp,
image/svg+xml) can be rendered as data URLs.
