docs: point public links to app.pinax.network (#547)

Replace thegraph.com docs links with the new Pinax-hosted help
center and docs site:

- Docs / Quick start → https://app.pinax.network/docs
- FAQ → https://app.pinax.network/help
- Authentication deep link → https://app.pinax.network/help#authentication

Updates README, skills/SKILL.md, and public/llms.txt. The Graph
network-ID references in src/types/zod.ts stay (they point at the
network registry, not the docs).

 For x402 clients, payment enforcement, verification, settlement, and metering are handled by the proxy layer before requests reach this API server. The API server exposes discovery metadata at `GET /.well-known/x402` and keeps request handling independent from x402 payment verification.
