Home: neue Startseite mit Weiterlesen, Weiterhören, Radio-Favoriten und Ambient; sw v87

- static/js/home.js rendert #tab-home aus dem, was die Seite schon hat:
  zuletzt gelesenes Buch (und drei weitere), laufende oder nächste Folge mit
  Restzeit und „N neue Folgen“, Favoriten-Sender (sonst die ersten
  gespeicherten) und zuletzt gehörter Sender, Drift mit der zuletzt
  gewählten Klangwelt und Sleep-Timer. Läuft im Browser, in diora desktop und
  in der Android-App (dort mit static/js/ kopiert).
- app.js: Tab 'home' (TOP_TABS), window.__dioraAmbientStart() lädt Drift bei
  Bedarf und startet es; die gewählte Klangwelt wird gemerkt und beim Laden
  wiederhergestellt.
- podcasts-web.js: Startseite Home, wenn nichts anderes gewählt ist.
- native-podcast.js aus diora-android 7dcc0c6 (Home in der Startseiten-Wahl,
  __dioraPodcastView).
