fix(PBI-63): sprint-switcher naar productpagina-header in productstijl

- Verwijdert setActiveSprintCookie uit sprint board page (kon geen cookie
  schrijven vanuit een Server Component — alleen Server Action / Route Handler)
- Verplaatst sprint-pulldown uit NavBar naar de productpagina action-row
  (dezelfde rij als 'Sprint starten' / 'Instellingen')
- Nieuwe SprintSwitcher-component in zelfde stijl als product-dropdown:
  truncated tekst + ChevronDown, geen status-badges
- NavBar krijgt activeSprintId voor sprint-link href; layout fetcht alleen
  nog activeSprint-id (geen volledige sprints[] meer)
