Benjamin Elder da8414bbd2 api: move the pause image from ActorTemplate to SandboxConfig (#848)
The pause image holds the sandbox's namespaces and runs no workload
code. It is an implementation detail of the sandbox, not something actor
authors pick, so it belongs with the sandbox binaries that already moved
off the ActorTemplate onto the cluster-scoped SandboxConfig.

It now travels with those binaries end to end: resolved from the pool's
SandboxConfig, carried on ateletpb.SandboxAssets rather than
WorkloadSpec, and recorded in the per-actor sandbox record so Checkpoint
pins it into the snapshot manifest and Restore rebuilds the sandbox from
the image the snapshot was taken with (the golden's on a DATA_ON_GOLDEN
restore). A record without one is rejected outright rather than pulling
an empty image.


- [x] Tests pass
- [x] Appropriate changes to documentation are included in the PR
