Huang Xin d2ff47029c fix(opds): detect XML feeds with leading whitespace, closes #4181 (#4190) ...

OPDS responses were classified as XML vs JSON with `text.startsWith('<')`.
Some servers (e.g. the Hungarian MEK catalog) return a valid Atom feed
prefixed with newlines/whitespace before `<feed>`, no `<?xml?>`
declaration, and a wrong `text/html` Content-Type. The naive check missed
the `<`, so the XML body was handed to `JSON.parse`, failing with
"Unexpected token '<' ... is not valid JSON".

Add a shared `looksLikeXMLContent()` helper that trims leading whitespace
(also stripping a UTF-8 BOM) before the check, and use it in both
`loadOPDS` and `validateOPDSURL`. Detection is now based purely on the
body, so formally-valid feeds with a bad Content-Type work.
