feat(feedback): "Idee teilen" lebt jetzt im PillNav-Usermenü

Ersetzt den schwebenden "Idee?"-Pill durch einen Eintrag im rechten
Usermenü (Profil / Credits / Idee teilen / Logout). Ein Affordance an
einer Stelle statt zwei nebeneinander.

- PillNavigation: neuer onFeedback-Prop + Lightbulb-Icon. Wenn gesetzt,
  ersetzt der Eintrag den Legacy-/feedback-Link in accountLinks und
  taucht zusätzlich oben in den userMenuBarItems (barMode) auf.
- UserMenuPanel: AccountLink kennt jetzt onClick? als Alternative zu
  href? — Action-Chips schließen das Panel direkt nach dem Klick.
- (app)/+layout: GlobalFeedbackPill-Mount entfernt, FeedbackQuickModal
  wird state-gebunden gerendert (moduleContext aus Pfad/?app= abgeleitet
  wie bisher in der alten Pill).
- GlobalFeedbackPill.svelte gelöscht — niemand referenziert sie mehr.
