authCapture: fix three review nits

- Drop the "deployed-chain list and" phrase from the cross-reference
  to the Canonical Addresses appendix; the chain table was removed in
  916bd37 so the link target no longer carries that.
- Broaden the invalid_deadline_ordering error description to cover
  all three legs of step 6, not just the refundDeadline < captureDeadline
  leg. The facilitator surfaces this for any of the three failure modes.
- Step 11 amount check phrasing was EIP-3009-leaning; spell out both
  authorization.value (EIP-3009) and permit2Authorization.permitted.amount
  (Permit2) so it's unambiguous.
