Feature request: Show validator status, waiting time in queue and aprox inclusion time

When the deposit itself is done, the user currently is left a bit in the dark about when the inclusion will happen or what the validator status is. Sure most validator clients will show, but I think it will be handy to tell the user the expected waiting time in the activation queue before or at least after the deposit is done.

No files, tests, or entry points are named. Start by tracing the post-deposit flow and identifying whether validator status, activation-queue wait time, and estimated inclusion time are available to the launchpad; done means presenting those values clearly before or after deposit completion.
