As a product manager, I want to know the general engineering effort, risks, and challenges associated with adding an optional dropdown selector for the grant ID in event registration configuration, so that organizers who have received a Wikimedia grant can have their impact (such as number of participants, contribution statistics)
more easily analyzed by WMF grant officers.

Acceptance Criteria:

• Investigate how we could include a selection system in the event registration configuration form so that:
  • The organizer can select the current grant ID
• Note that this could be a dropdown or search, but the organizer should pick the grant ID rather than manually typing it so they can reduce human error
• Once the grant ID is saved, it should be displayed to (at minimum) event organizers and WMF grant officers
• We should explore if displaying the grant ID to everyone would help reduce the scope of the MVP (and by how much)
