Allow UI to build against latest agoric-sdk

[mhofman]

Take on explicit @endo/marshal and @endo/captp dependencies to satisfy parcel-bundler. Preliminary CI fix for Agoric/agoric-sdk#4433.

Also minimally reorganizes some dependencies between dev and prod. This does not switch the @agoric deps away from *, leaving in place older dependencies in yarn.lock, since the current usage is through a linked agoric cli.

cc @kriskowal, I'll let you handle the agoric install dev ceremony, since you'll have to manually update some package.json for the packages moving to endo.

I don't want to complicate things as long as this is working, but does it break if we keep those as devDependencies? In the wallet UI, for example, everything is a devDependency because there's no production service running, just the dev server and build script.

There are changes in 2 directions:
parcel bundler is clearly a dev dependency, so moved that there.

Then I usually consider anything that gets bundled into the runtime as a prod dependency, not a dev dependency for static apps, which I believe dapps are. I'm happy to revert this if that's not how we structured the ui of our dapps.

SGTM, as @michaelfig mentioned, trimming down the runtime deps is only significant in the SDK, and we can use this more regular approach in the static dapps
