Routenplanung auf HAFAS (/journeys) umstellen, Zwischenhalte, Filter, Paginierung

Löst die WebApp aus der eigenen OTP2-Instanz heraus und nutzt dieselbe
HAFAS-Anbindung (VBB + Deutsche Bahn) wie die iOS-App, damit beide Clients
gegen dasselbe Backend-Feature-Set laufen:

- js/api.js: getJourneys() ruft jetzt /journeys statt /otp/journeys auf,
  inkl. via0-2 (Lat/Lon/Name/WaitMinutes), modes, bike, earlierRef/laterRef.
  Gibt die volle Antwort zurück statt nur { journeys }.
- js/app.js: bis zu 3 Zwischenhalte mit eigener Ortssuche und Aufenthaltszeit,
  Verkehrsmittel-Filter (ModeFilter-Komponente wiederverwendet), Fahrrad-
  Toggle, Früher/Später-Buttons zum Nachladen. Share-Link-Format um
  Vias/Modes/Bike erweitert, alter Umstiegszeit-Puffer entfernt (von HAFAS
  nicht unterstützt).
- index.html/styles.css: neue Formularelemente für Zwischenhalte, Filter
  und Paginierung.
- js/i18n.js: neue Übersetzungsschlüssel in DE/EN, alten sourceNote-String
  korrigiert (& wurde per textContent gesetzt und wäre literal
  angezeigt worden statt als &).
- README.md: Feature-Beschreibung aktualisiert.
