The E2E tests can be run in plugin (`docker compose`) or standalone
(`docker-compose`) mode. Existing logic was in place to ensure that
the helper method is always used, which will invoke the right one
based on how tests are being executed.
However, this logic was too easy to (unintentionally) bypass given
the myriad of ways that commands can be run. The check has been
made stricter and pushed to a lower-level to more aggressively
catch instances.
As a result, a bunch of calls to `RunDockerCmd` are now updated
to be `RunDockerComposeCmd`, which will ensure that the invocation
is correct based on test mode.

When running Docker / Compose commands, do NOT inherit the system
environment to ensure that the tests are reproducible regardless
of host settings.
Additionally, per-command environment overrides are provided to
the command instead of using `os.SetEnv`, as this is not safe when
running tests in parallel (`testing.T::SetEnv` will actually error
if used in this way!)

The big mechanical change here is to NOT store `t` as a field on
the `CLI` object (which has been renamed as well to fix the odd
capitalization). The way the tests are structured meant that the
"subtests" were using the _parent_ `*testing.T` instance, which
causes various oddities including confusing messages on failure
about a child test causing a panic in the parent.
Additionally, a few tests have been blocked from running in
parallel because they are sharing `compose.yaml` fixtures and
can fail as a result (e.g. due to a port conflict on the host).
I'll fix these in follow-up PRs but want to focus on correctness
for the tests before optimizing them.
