Overview

This PR resolves configuration from env variables first for server with transactions and with tiles. The orFalse on the flag was necessary to turn it into an Opt[Bool], but it was also making it so that the CLI

Checklist

• New tests have been added or existing tests have been modified not super straightforward to test configuration options 😢 maybe continuous configuration testing will help with some ideas

Testing Instructions

• fire up sbt with the env var config: API_WITH_TRANSACTIONS=true ./sbt
• start the server: application/run serve --db-host=localhost
• check the api spec -- http :9090/open-api/spec.yaml | grep delete -- you should get a hit
• stop the server
• start again with the tile flag -- application/run serve --db-host=localhost --with-tiles
• check the api spec -- http :9090/open-api/spec.yaml | grep tiles -- you should get a hit
• make sure transactions are still there as well -- http :9090/open-api/spec.yaml | grep delete -- you should get a hit
• stop sbt
• start it again, this time with the tiles env var: API_WITH_TILES=true ./sbt
• check for tiles in the spec, then add --with-transactions and check for both -- you should expect hits

Closes #969
