Subject: [PATCH] feat: add MaximumSats L402 endpoints to API directory

Add 5 MaximumSats endpoints for Bitcoin/Lightning developers:
- BOLT11 Decoder (10 sats)
- NIP-05 Verifier (20 sats)
- Web of Trust Report (100 sats)
- npub Decoder (5 sats)
- Lightning Address Resolver (15 sats)

MaximumSats provides Bitcoin tools and APIs powered by Lightning,
making it a great complement to the existing x402 ecosystem.
