feat: add react front end

[stringhandler]

Description

Adds a react front end.

There are still some problems with it, but mostly they lie in the backend of launchpad and can be fixed in other prs.

To Test

If you want to run it, you will probably need to build the react first.

cd ui/react2
npm install
npm run build
cd ..
cargo run --bin tari_bus_tauri

I could build debug and release mode but only an empty app opens.

Hi, some feedback w.r.t. the TUI operation after this addition:

• The Wallet payment address does not show the emoji_id anymore

All else seems fine

Tested the continued correct functioning of the TUI operation - ACK
