feat: refactor organisation pages with tabs, members tab, and danger zone

Organizer org page (/organisation):
- Timestamps moved below title as muted caption
- VTabs with Algemeen (details) and Leden (members) tabs
- Members content embedded from separate page with full functionality:
  invite, edit role, change email, remove, pending invitations

Platform org detail (/platform/organisations/[id]):
- Timestamps moved below title alongside slug
- VTabs with Algemeen and Leden tabs
- Danger zone redesigned: type-to-confirm delete dialog, disabled
  Transfer Ownership button with "Nog niet beschikbaar" tooltip

Navigation:
- Removed standalone "Leden" menu item (now a tab on org page)
