Cleanup UI buttons + smarter series-aware search title

UI: Hide developer tools (Cover-aus-Datei, Tags-lesen,
Connectivity-Check) behind a '+ Tools' toggle. Default view has only
Play, Match, Auto-Match. Tag extraction runs automatically on scan
anyway, so the buttons were noise.

Matcher: Item metadata (series, author from tags or earlier matches)
now flows into the search:
- detect_series() also scans inside title, not only prefix — handles
  garbage chars (◆ U+25C6 etc.) before the series name
- New _strip_series_prefix removes "Die drei ???" from search title so
  APIs see only the episode title ("Die Villa der Toten") which is how
  most databases index these
- _build_search_title also strips non-printable / exotic chars and
  bracketed content anywhere (not just trailing)
- Effective series falls back to item.series when detect_series misses
- Search call now logs which series the search is using

Example: title='◆Die◆ drei ??? Die Villa der Toten (drei Fragezeichen)'
  detected_series='Die drei ???', search_title='Die Villa der Toten'
