feat: smart contract setTokenVerified calls through ethers (#272)

* feat: add scripts to create lambda layers

* chore: deploy the new version of the contract to mumbai.

* feat: update environment variables used in the serverless config.

* feat: add JSON_RPC env var.

* feat: add deploy:dev command.

* feat: functional deployment script, configuration changes.

* feat: update config and the deploy script.

* docs: add the serverless stack diagram

* feat: move the ABI to the lib dir, update the build handler + some minor changes on the config files.

* feat: add ethers to the library, send transactions through the contract instance.

* fix: make the ethers transaction signing work, update handlers accordingly, customize prisma logs, update the config files to match the changes.

* feat: remove logs, log specific errors for environment variables, update hardhat config.

* feat: add support for the --stage flag in the deploy script.
