Handle jobs with deleted pods

[dnephin]

Fixes #6272

Check for the condition where a job is completed but no longer has pods, and set those to state.Terminated to indicate they are ready.

Tested manually using the steps described in #6272, and added a unit test that fails without this change.

thanks for investigating this!

let me poke around a bit before we merge this approach. historically, we try to keep "status interpretation" as low level as possible, or you get weird bugs where multiple layers are interpreting the status differently.

Another option I had considered was to remove the || res.Type == v1alpha1.TargetTypeJob from

tilt/internal/controllers/core/session/status.go

Line 101 in 38238ec

} else if res.State.Active != nil && (!res.State.Active.Ready || res.Type == v1alpha1.TargetTypeJob) {

, but that seemed weird because then a job could be ready in two different states (either terminated, or active and ready).

i re-rolled this into #6276, which has some additional integration tests. ya, i think removing the || res.Type == v1alpha1.TargetTypeJob is the right change.
