chore: parameterize integration tests

refactors integration tests to execute identically across runtimes

with this change, we can also specify tests to run with the integration-test script (e.g. `integration-tests TestLifecycle` — all tests are fully encapsulated and can execute alone). providing no option will run all tests.

tests have been split into the following:

- TestLifecycle (init, deploy, call)
- TestHttpIngress (tests all http methods and tests aliased fields)
- TestDatabase
- TestExternalCalls (kotlin -> go call, kotlin -> kotlin call, etc. for all runtime permutations)

a couple small changes captured by the integration tests are also included in this PR:
- Database.kt converts module name and DB name to uppercase to align with the Go DB SDK
- Kotlin schema extractor includes module names for all DataRef schema objects, even those declared in the referencing module (this fixes builtin.HttpRequest/Response types for HTTP ingress in Kotlin)
