feat(claims): add x_fc_pages_11_12_in_original + computed gate

New boolean on sale.order tracks whether pages 11 & 12 are bundled
inside the original application PDF. Computed helper
x_fc_has_signed_pages_11_12 ORs bundled flag with separate-file and
remote-signing presence so downstream gates can read one field.
