Addresses bitcoin-dot-org/Bitcoin.org#1216.

This expands the Verifying Payment section with more detail about accepting zero-confirmation payments, including:

  • why mempool visibility is not consensus
  • how zero-conf double-spend risk differs from replacing a confirmed transaction
  • stuck/evicted/replaced unconfirmed transactions
  • practical checks for receivers who choose to accept zero-conf payments
  • why CLTV/CSV can constrain specific protocols but cannot make unrelated zero-conf payments final

Validation:

  • python -m sphinx -b html . _build/html succeeds
  • git diff --check passes

The Bitcoin.org bounty instructions mention adding a bitcoin address in an accompanying note/comment. I can provide a receiving address in a follow-up comment if this PR is considered eligible.
