…uilt docker image (#1244)

* chore(build): give local gradle builds more memory

Match what github actions uses to prevent e.g.

* feat(docker): add HEALTHCHECK

to facilitate testing container startup

* feat(build): add igor-integration module to exercise the just-built docker image

* feat(integration): run integration test in pr builds

multi-arch with --load doesn't work, so add a separate step using the local platform to
make an image available for testing.

see docker/buildx#59

* feat(integration): run integration test in branch builds
