Build Cleanup & Dependency Minimization

[Additional Slack context](https://2dimensions.slack.com/archives/C03GXT15JKX/p1733267916478549).

After our discussions around `androidx.core:core-ktx`, I did some investigations and it turns out we don't need it at all at the library level. This allows users to use any version they want, without impacting their `targetSdk`.

This lead me down the path of wondering what other dependencies aren't necessary. So one by one I disabled them checking if it would break the build. In a couple instances I was able to go from a "bundle" dependency to only the exact sub-dependency required, e.g. `"androidx.test:core-ktx:1.6.1"` -> `androidx.test:runner`.

There's also a bit of other minor housekeeping as I was poking around in these files.
