Breaking Changes

• API Configuration has been consolidated into one config file, config.prod.json.
  To migrate, check out: https://github.com/Receipt-Wrangler/.github/blob/main/configuration/configuration.md for the new structure, and simply move the database env variables from the docker compose, and the feature config values to config.prod.json.
  Check out: https://github.com/Receipt-Wrangler/.github/tree/main/examples for some examples specific to your database type.

• openApiKey has been removed from the configuration. To migrate, use the aiSettings in the config file instead as shown here: https://github.com/Receipt-Wrangler/.github/blob/main/configuration/configuration.md
