feat: migrate bitcoin generate txs, closes LEA-1735

[fbwoolf]

This PR migrates code to generate the unsigned psbt for btc sends.

I did some refactoring here using generic types so we can extend our form context to accommodate diff form data in each form flow. I needed to do this to handle loading feeRates and utxos for bitcoin specifically. I spent a lot of time trying to rethink this and hope it is a good solution. I've created a few more loaders to get rid of some undefined returns we had in the code I ported over from the extension.

I've also spent some time making sure to write tests that were missing, and refactoring bitcoin fees code as I migrated it over.

As mentioned in Slack, I'd like to standardize our Fees model type after this work.

Great work @fbwoolf, like the component generic 👍🏼

[edgarkhanzadian]

Amazing work!! 🚀

[edgarkhanzadian]

nit: i think it's better to keep this function as a pure function and then wrap it in useCallback in the component when we need it.

[kyranjamie]

+1 this doesn't need to be a hook as it's not using any state. useCallback isn't needed if it's defined outside of react

[fbwoolf]

Good point, thanks, will change.
