Separate workflows for per-PR CI and smoke test

[delucchi-cmu]

There's currently only one github workflow for the template that runs in all CI triggers. If possible (maybe after we've migrated to pytest-copie for template tests), it would be nice to have separate workflows for smoke test (with manual trigger) and for general PR and main-merge CI.

This mirrors the best practice we have in hydrated projects.

We should also update the workflow dashboard to have separate "nightly" and "live build" workflow entries.
