fix: Update tsconfigs to resolve IDE type errors

[pulpdrew]

Summary

This PR updates the structure of our tsconfigs so that IDEs (namely, VSCode) can successfully typecheck test files (which were previously excluded by the default tsconfig files in each package.

The new structure is as follows:

• Each package has a tsconfig.json. This is where the bulk of the configuration is, and is the file read by VSCode. It includes both source and test files.
  • The api and common-utils tsconfig.json each extend from the same tsonfig.base.json in the root directory, since they had quite a bit of shared configuration. The app package's tsconfig is sufficiently different that sharing a config between app and api was less helpful.
• Each package has a tsconfig.build.json file. This extends the tsconfig.json and excludes test files. This file is used during builds (next build for the app package and tsc for the api package)
  • The common utils package is built using tsup, which does not run typechecking, so there is no need for a tsconfig.build.json in the common utils package. The tsconfig.json in the common utils package is used for linting, and both source and test files will be linted.

Testing

IDE errors on test files are gone:

Is it possible for us to share the tsconfig base across api and app using this config, or are they fairly diverged?

[pulpdrew]

The api and common-utils configs had a lot of overlap, so I created a tsconfig.base to share between them (great idea!). There was a lot less overlap between app and the others though, so I didn't think it would be worth it to create a base config that all three packages could share

Nice, should I try it locally? It looks good to me from my scan of the changes

[pulpdrew]

Yeah, if you could confirm the IDE type issues are gone for you locally as well, that would be great!
