feat: gateway link using edge gateway worker binding

[vasco-santos]

This PR makes nftstorage.link to use new reads pipeline with worker binding to https://github.com/web3-storage/reads/tree/main/packages/edge-gateway . It is quite similar to https://github.com/web3-storage/w3link/tree/main/packages/edge-gateway-link but with different configurations.

Notes:

• most of the tests live now in the reads pipeline given this repo is mostly an entry point to there for now (future might reserve special features for product specific gateway)
  • this means no need for Docker here for instance, given we do these tests with testcontainers in the reads pipeline
• worker binding not to perma-cache API but to reads worker (reads worker interacts with the API)
• use loki for metrics instead of logtail + metrics endpoint
• durable objects removed 🎉

Needs before merge:

• [x] secrets setup
