[Enhancement] Pouch takes a .webhapp instad of a .happ + ui.zip

[mattyg]

Does it make sense for the pouch to hold a .webhapp, instead of both a .happ and a ui.zip? Seems simpler, right?

Absolutely, I actually wanted to start implementing this recently but ended up not prioritizing it. One thing that held me off from implementing it is that unpacking a webhapp is easiest via using the hc CLI and this would require hc to be present in the environment, i.e. probably nix shell. I guess that's acceptable but relying on nix seemed like an additional point of friction as well.

We should be able to use hc_bundle directly, right?: https://github.com/holochain/holochain/blob/78ae6e3a7d69a906e6112b09fada7ac43b0b1eea/crates/hc_bundle/src/cli.rs#L192

Note that the unpacking needs to happen at build time, not runtime. But it might still be possible to use it in a build.rs file, will have to look into it.
