Custom graphs can have registration custom questions, but haven't had ticket questions added yet. We want ticket questions to work with graphs like registration custom questions.

Definition of Done

• ✅ Ticket questions that have options can be added to custom graphs
• ✅ Graphs can be saved with ticket questions
• ✅ Graphs with ticket questions load correctly
• ✅ Ticket questions are considered ticketing type in graphs (will be hidden if any registration related option has already been selected and will make all registration related options be hidden when selected)
• ❌ Existing graph options still work
• ❌ Graphs still copy correctly when copying events (if a category or other item does not get copied, graphs using that item will still be copied but the parts that reference that item will not be copied)
