feat: dev environment backend setup (#278)

* feat: add anvil (qanet) to hardhat config networks.

* chore: deploy contract to anvil testnet.

* chore: sepolia deployment.

* merge: authentication sls.

* feat: separate the issignaturevalid function from handlers.

* feat: update subgraph config to match the qa network.

* feat: add app specific prisma schema to deploy script copy command.

* fix: merge conflict

* feat: remove unnecessary conditions.
