[ZDF] Overhaul ZDF extractors

* pull some yt-dlp changes into ZDFBaseIE._extract_format()
* add test cases from yt-dlp to ZDFIE
* fix crash in ZDFIE._extract_mobile() when object had no `formitaeten`
* improve title extraction in ZDFChannelIE (remove trailing station ident)
* avoid extracting non-video playlist items (fixes #31149)
