Set Event Hosts

As a Host, I want to set a list of users as hosts of an event, So that multiple people can manage and coordinate the event together.

Acceptance Criteria

• Given I am creating or editing an event
• When I set event hosts
• Then I can select from a list of available users in the system
• And I can add multiple users as hosts
• And I can remove users from the host list
• And the event creator is automatically included as a host (cannot be removed)
• And each host can:
  • View the event details
  • Edit the event (if permissions allow)
  • Manage the guest list
  • Manage the menu
  • Generate shopping lists
  • Update event status
• And all hosts are displayed on the event detail screen
• And I can see which users are hosts vs. guests for the event
