Finally updates to react 18.
This is actually the third attempt to do so - but there were always to many PRs waiting, which would have introduced many merge conflicts. Now in calmer times, it was picked up again.

Run npm install after checkout.

This updates most dependencies to their most recent versions.
Some behaviour had to be adapted (e.g. "success" step after importing a wallet), but all-in-all, it would work exactly as before.

Also noteworthy:

• had to insert a "success" step after wallet import flow as a workaround (navigate did not work anymore)
• finally "typescript-only" - disallow new js components

How to test

• Checkout the branch
• Run npm install
• Run npm run dev:start
• Verify everything is working as before (please test "create wallet", "import wallet", "sending", "fidelity bonds", etc.)
