fix(badges): sync create form badge types with search filter; default to attendee

- default_badge_type_code_li now matches ae_comp__badge_search.svelte list
  (attendee, sponsor, staff, guest, volunteer, member, nonmember, test)
- badge_type_code initializes to 'attendee' (In-Person Attendee)
- $effect re-applies preferred default when template badge_type_list loads async,
  falling back to first item if 'attendee' isn't in the template's list
- Remove the blank '-- Select Badge Type --' placeholder option
