feat(scheduler): invert external/internal toggle

[dergigi]

This PR inverts the external address toggle and adjusts the behavior of the scheduler to "internal" by default.

Also adjusts and updates copy, fixing #248

That's a good change! Much clearer than before. 👏 👍

One issue though: When the screen initially loads, the internal destination addresses won't be set and the button "Start" button will be disabled. That's because the internal addresses will only be set once the toggle is actively un-toggled. Only after toggling the button back and forth will the internal addresses be set and the button be activated.

With the new logic, we'll need to provide internal destination addresses as default values for the address fields.

Pushed a fix that should work (I hope). TL;DR: Waits with rendering the form unil the wallet is loaded. Once the wallet is loaded, sets the form's initial values to 3 internal addresses.

@theborakompanioni Can you have a quick look please? 🙏 Don't want to approve my own code. 😅

Issue should be fixed
