Fix queue page badge warning for badgeless conventions (#10183)

[nbudin]

Summary

Fixes #10183 - Queue page was incorrectly displaying a badge warning even when the convention was configured as badgeless (ticket_mode: disabled).

Changes

• Added ticket_mode field to the MySignupQueue GraphQL query
• Updated NextRoundInfoBox component to check the convention's ticket_mode before displaying the "no ticket" warning
• When ticket_mode is disabled, the component now returns 'ok' status and suppresses the warning

Behavior

Before

• Badgeless conventions would show: "You do not have a badge. You will not be able to sign up for games until you have purchased a badge."
• This was confusing since the convention doesn't sell badges

After

• Badgeless conventions no longer show the warning
• Conventions that require tickets still show the warning appropriately
• Users in badgeless conventions see the normal info box without any badge-related warnings

Test plan

• Test with a convention where ticket_mode is set to disabled (badgeless)
  • Navigate to the signup queue page
  • Verify no badge warning is displayed
• Test with a convention where ticket_mode is required_for_signup
  • Navigate to the signup queue page without a ticket
  • Verify the badge warning is still displayed correctly
• Test with a convention where ticket_mode is ticket_per_event
  • Verify appropriate behavior for this mode
