Sonnensystem: Aufgaben + Onboarding-Info in den Header (eigene Icons)

- obs-open-btn (Aufgaben, Klemmbrett-Icon) + obs-help-btn (Onboarding,
  Info-i-Icon) in den Header vor die Musik verschoben; obs-launcher weg.
- Redundantes help-toggle (moonTilt-?) aus dem Header entfernt, Handler
  null-sicher (moonTilt weiter ueber Inline-? in der Mondbahn-Sektion).
- obs-Pill-CSS neutralisiert (Header-Stil greift).
