Add public genesis receipt proof page and site links

[GsCommand]

Motivation

• Provide a dedicated public UI for retrieving and cryptographically verifying stored genesis receipts by ID, separate from the existing receipt model and manual verifier pages.
• Surface the production-proven stored-genesis lookup flow (POST /api/verify-id → GET /api/receipts/:id) without changing verification or receipt-generation backend logic.

Description

• Add a new public page public/genesis-proof.html implementing the verification-by-ID UI with required metadata, hero copy, input (Genesis Receipt ID), submit behavior, visible states (IDLE, LOADING, VERIFIED, INVALID, RECEIPT NOT FOUND, ERROR), copy buttons, and JSON panel; it posts to POST /api/verify-id and on success fetches GET /api/receipts/${encodeURIComponent(receiptId)} to show public receipt JSON.
• Render only safe verification fields provided by the existing API: status, receipt_id, receipt_type, agent, verb, signer, and verification booleans hash_matches, signature_valid, and ens_resolved, plus public_key_source and key_id when present from POST /api/verify-id responses.
• Add focused, non-breaking site links/cards pointing to /genesis-proof.html from the verifier (public/verify.html), receipts (public/receipts.html), homepage (public/index.html), docs home (public/docs.html), protocol (public/protocol.html), live proof (public/proof.html), production proof (public/stack-proof-demo.html), and the API reference (public/api.html), and include a compact developer example for POST /api/verify-id in public/api.html.
• Preserve existing pages (/receipts.html, /verify.html, existing API handlers) and do not alter cryptographic/verification backend code or genesis generation logic.
• Small site polish fixes (minor CSS/class consistency edits) and ensured canonical/Open Graph metadata for the new page.

Testing

• Ran npm test and all tests passed (125 tests passed, 0 failures), including api/verify-id and GET /api/receipts/:id contract tests that exercise VERIFIED, INVALID, and RECEIPT_NOT_FOUND flows.
• Ran npm run check:links and the local link checker reported all local links/assets resolved across the site.
• Ran cd examples/webhook-auto-verify && npm run check (example checks) and it passed.
• Performed static assertions on public/genesis-proof.html to check required copy and absence of forbidden admin/payment tokens, and loaded the page via a local static server to confirm it serves correctly (local curl load check succeeded).
