BREAKING CHANGE: remove @agoric/wallet-ui

[turadg]

closes: #6474

Description

Per #6474, the Wallet app code is now at https://github.com/Agoric/wallet-app.

This PR removes it from agoric-sdk so that there is just one canonical Wallet UI. I believe that the instructions for using the older version compatible with ag-solo still work since they check out community-dev and not master. (Indeed, master wallet-ui is already broken for agsolo)

Security Considerations

Improves separation of builds and dependencies.

Documentation Considerations

End users are not affected.
Developers who wish to contribute to the Wallet app will need to know about the new repository. This commit message directs them.
Ag-solo users will need to use the instructions above to get an older version. (We've already decided agsolo doesn't need a GUI going forward).

Testing Considerations

CI

1. We plan to add it to wallet-app before merging this right?
2. Will we move web-components to a separate repo too as part of pull web UI out of agoric-sdk #6474?
3. I wonder if there's now some things we can prune from yarn.lock. @mhofman might know better how to clean that up.
4. I know @michaelfig was doing some stuff around ag-solo so I want to defer approval to him

[mhofman]

Oh cleaning up yarn.lock would be much appreciated!

It's already there, per the first line of the description. Specifically: https://github.com/Agoric/wallet-app/tree/master

2. Will we move web-components to a separate repo too as part of pull web UI out of agoric-sdk #6474?

That's not part of 6474. I'm not opposed but it would need some discussion as to where it goes and how it gets published.

3. I wonder if there's now some things we can prune from yarn.lock. @mhofman might know better how to clean that up.

Good call. I meant to include that and forgot. Here's my local,

[6474-extract-wallet-app a53bf6480] chore: yarn install
 1 file changed, 239 insertions(+), 5496 deletions(-)

18536 lines down to 13729, 26% reduction. I'll hold off on push until approval since that's liable to get stale as master changes.

4. I know @michaelfig was doing some stuff around ag-solo so I want to defer approval to him

Ok, I'll make him the sole reviewer.

Oh okay I had trouble finding it. Why master instead of main?

[michaelfig]

LGTM. Can you please update yarn.lock as well?

[mhofman]

Any reason integration was bypassed for this?
