fix(ui): label default key type as "Full Access" on key edit page (#29870)

The key edit page showed the default key type (no allowed_routes restriction)
as "Default", while the key creation form already labels the same value
"Full Access". Align the edit page to the create form so the two surfaces agree
on both the label and its description.
