feat: daily activity summary email

- activity-email-actions: sendDailySummaryAction — filters today's
  activities by dueDate, sends personalized email via Appwrite Messaging
  - 'me': current user's activities only
  - 'team' (owner/admin): each member gets their own activities separately
- send-summary-dialog: dialog with me/team radio (owner/admin only sees
  team option), inline error + toast on success
- activities-client: 'Günlük Özet' button in header, role prop added
- activities page: passes ctx.role to client
