chore(commerce): scrub internal disclosures from public-package source

Mirrors the node-commerce sweep on the python side:

- Removed "pending_identity" (internal order-state column value) from
  _TEMPO_WARNING + _X402_WARNING in agent_instructions.py and from the
  default llms.txt template; agents see "the order will not complete"
- Tightened the agentscore-pay tool description from "x402 on Base + Solana"
  to "x402 on Base and MPP on Tempo + Solana" so the rail-protocol mapping
  matches the 1.4.0 reality (Solana goes through MPP solana/charge)
- Genericized docstring examples in identity/a2a.py, identity/ucp.py,
  discovery/skill_md.py, challenge/order_receipt.py: "Martin Estate" +
  "agents.martinestate.com" + "wine-purchase" placeholders replaced with
  "Example Merchant" / "agents.example.com" / generic skills
- examples/multi_rail_merchant.py docstring renamed from "Martin-Estate-
  style" to "regulated-commerce" to describe the pattern, not the customer

Mintlify worked-example pages keep referencing Martin Estate by name;
that's allowed at the marketing/URL level per the disclosure-posture rules.
