PM-Tracking: Ereignis-Log fuer Aufrufe + Shares (press_release_events)

- press_release_events (type view/share, channel, ohne Personenbezug):
  Model/Enums/Factory, Cascade-Delete an der PM
- Detailaufruf loggt View-Event zusaetzlich zum Legacy-hits-Zaehler
  (bleibt bewusst einfacher Page-Request-Zaehler, User-Vorgabe 10.07.)
- POST press-release/{slug}/share (throttle 30/min, nur archiv-sichtbare
  PMs des Portals) loggt Teilen-Klicks je Kanal (LinkedIn/X/E-Mail/Copy)
- Kundenpanel-PM-Seite: neue Kachel Geteilt mit Kanal-Aufschluesselung
- lang: web.detail.views (de/en)
- Tests: Web/PressReleaseTrackingTest (7)
