Add "custom creature" option to bestiary suggestions dropdown

When typing a name that partially matches bestiary entries, users
couldn't access the custom creature fields (Init/AC/MaxHP). Now a
prominent option at the top of the dropdown lets users dismiss
suggestions and add a custom creature instead, with an Esc hint.
