fix(pwa): Layout berücksichtigt iOS-Safe-Area auch im Hauptbereich

Bisher bekam nur .topbar Safe-Area-Padding, aber .content-wrapper
rechnete weiter starr mit --topbar-h. Im PWA-Standalone-Modus auf
iPhones mit Notch lief der Kalender dadurch oben in die Status-Bar
und unten in den Home-Indicator hinein — die Wochentag-Header und
Tagesnummern der ersten Zeile waren verdeckt, die letzte Zeile
zu kurz.

- .content-wrapper: margin-top und height berechnen jetzt safe-top
  und safe-bottom mit ein
- .sidebar (Mobile-Overlay): top startet ebenfalls unterhalb der
  vergrösserten Topbar

Version v10 → v11.
