feat(sasquatch): Pro receipt DM + local Pro FAQ + tougher free-tier answers

1. Pro purchase confirmation: on a paid pass, send the buyer an encrypted
   NIP-17 receipt to their own inbox (tier, expiry, unlocked perks). Best-effort
   so it never blocks the purchase. Success toast now points to the DM.

2. Frictionless Pro answers: add local static-FAQ entries for "sasquatch pro",
   "pro perks/version", pricing, "go pro", "upgrade" — so those questions are
   answered instantly and never dead-end when the free AI model is rate-limited
   (the exact failure seen when asking "what perks has the pro version?").

3. FAQ matching now prefers the longest matching key so specific phrases win
   over broad ones ("sasquatch pro" > "pro").

4. Refresh the free-model fallback list (add deepseek-v3, gemini-2.0-flash-exp,
   qwen-2.5-72b) for better free-tier AI availability.
