fix: render product detail pages on TYPO3 13

- ObjectManager replaced by GeneralUtility::makeInstance(), the
  services fetched that way are public
- QueryBuilder::add('orderBy') and the remaining execute() calls,
  detailAction returns a response
- PHP 8 warnings for missing array keys (same values as on PHP 7.4)
- Webcam images are external URLs: plain img tag, f:image only takes
  FAL files
- typo3_encore 7 needs the PKG:ssch/typo3-encore: prefix and
  external = 1 so TYPO3's path check does not drop the entry
- CDN image rewriting as a middleware instead of EXT:replacer, which
  is not PHP 8.5 clean; same pattern, only for page responses
- vhs 8 for the ViewHelpers the templates use
- OpenGraph meta tag manager skips the backend
- myEpUrl with trailing slash as in production
