fix: Zeitsteuerung reparieren und vervollstaendigen

Der vorige Commit 26efed8 war nicht lauffaehig - fehlgeschlagene
Patch-Anwendungen hatten Zeilen aus ihren Bloecken geschoben.

Reparaturen:
- admin(): zerschossene Playlist-Schleife neu aufgebaut
- player(): return render_template war in den else-Zweig gerutscht,
  wodurch die View bei aktiver Priority-Playlist None lieferte (HTTP 500)
- playlist_item_enabled() existierte nicht mehr (umbenannt zu
  is_item_active), zwei Aufrufe im Player blieben stehen -> NameError
- update_playlist_item(): Absturz bei new_url=null, und der
  enabled-Status ging beim Bearbeiten verloren
- Dateityp-Erkennung mit else-Fallback, ftype konnte ungebunden bleiben

Zeitsteuerung:
- Zeitfenster ueber Mitternacht (22:00-02:00) funktionieren; bei weekly
  gehoert ein solches Fenster zum Wochentag seines Starts
- Optionaler Gueltigkeitszeitraum (valid_from/valid_until) fuer daily
  und weekly, beide Grenzen einzeln optional und inklusiv
- daily/weekly speichern nur noch die Uhrzeit ("08:00") statt eines
  Zeitstempels mit bedeutungslosem Datumsanteil; _schedule_time() liest
  weiterhin auch Altbestaende mit vollem ISO-Zeitstempel
- playlist_hash() bezieht den ausgewerteten Aktiv-Zustand ein, sonst
  bemerkt der Player ein ablaufendes Zeitfenster erst beim naechsten
  Reload aus anderem Grund
- Zeitsteuerung auch fuer Datei-Eintraege, nicht nur URLs
- Neuer Filter schedule_text fuer den Tooltip am "Zeit"-Badge

Oberflaeche:
- required lag auf ausgeblendeten Feldern und blockierte das Absenden
  des Formulars "URL hinzufuegen" ohne sichtbare Meldung
- updateScheduleDaysVisibility() war innerhalb von DOMContentLoaded
  definiert, der Edit-Handler darueber -> ReferenceError bei jedem Klick
- data-schedule mit tojson zerlegte das Attribut, da tojson " nicht
  escaped
- Zeitsteuerungs-Block als schlichte Formularzeilen statt als card, die
  global den roten Rand und grauen Header erhaelt
- Zeitsteuerung auch in der Priority-Playlist
