Apply dyn-cfg to p1 cases

[snadrus]

Make our Ingest & Address configuration dynamic such that the values apply instantly.

Market will ERROR on 0 <--> 1 that a restart is required to enable the correct services.

Discoveries
Computed Values: These become their own config.NewDynamic() which gets updated by a callback on the source(s).
I could be persuaded to turn these into event streams into reactive programming: https://github.com/samber/ro

I don't think we should be stopping & starting services on these changes. That will simply be unsupported.

Bad configuration is setup to throw error and reuse the original in all the secondary-interpretations, otherwise it'll stream out errors until fixed in the direct consumptions. These seem reasonable.

I couldn't get TOML to do value unmarshal as it knows documents only at the top level, so I built an ugly wrapper full of reflection that we should use instead of TOML unmarshal. It works, but it's ugly.

BTW, also made descriptions visible (was a mouseover). This will make it easier to see what's dynamic and what's not.

We should Test this with UI and see if new encode/decode works with our weird UI setup.
