feat: list Peer Pay merchant groups

[Kartik4152]

Summary

• Lists the new Peer Pay merchant groups (production + staging) under a new peer-pay curator.
• Groups were created on-chain on Base (8453) on 2026-07-31 in the same AddressGroupRegistry deployments as the existing Peer listings.
• Members are live Peer Pay merchant wallets, curated manually by the Peer Pay team via the Peer Pay admin dashboard, plus the group curator and the Peer Pay signal relayer.

Changes

• groups/peer-pay/peer-pay.json — production group 0x174b8a29536721a3eae290bfd55651b85a53fc334b971d993fa93ed8dde15e48 on registry 0x39f80118f9eb619135f116171b6cb91d372c5af2
• groups/peer-pay/peer-pay-staging.json — staging group 0xc82c20c00033046a2f017b65532d7148a337282f17c73296663a530e49ba00f7 on registry 0x54ff7788cb42b46fe2f016a65fd0f654bb9bcf3d

On-chain verification (for reviewers)

• Curator/owner of both groups: 0x90c0b97aec997b5bce93f290d646b3e3223dfe6c (dedicated Peer Pay curator EOA) — matches curator.address in both files.
• Production: created in tx 0xd90991afb5bf437ad5126dd7ff6f10f4e3394708f26b46a33994b3fb61608283 (block 49328184); members seeded in 0x21bd748e908375f602486b63a355f551e269172880f6648dbd45625c82861d76.
• Staging: created in tx 0x6531b7faa1e1b3a76e4853f4fb8a7972ac64bc2acb60ecf55a7746aa396760a7 (block 49328129); members seeded in 0x7b9a7cae481d7b92ab3873b8b43481de8fa6755043357c9dc2b12ad65297dc90.
• getGroup on each registry returns exists=true with the curator above; no resolver set.

Test Plan

• npm run check passes locally (10 groups validated and built)
• getGroup(groupId) verified on both registries (curator match, exists)
• File paths match groups/<curator-slug>/<group-slug>.json validation rule
