feat(ledger): add utf-8 message signing support

[kyranjamie]

Try out this version of the Hiro Wallet - download extension builds.

This PR adds support for UTF-8 message signing for Ledger.

I've refactored many duplicated components, yet retained an approach where each Ledger interaction is composed of generic components, making use of Route state where action-specific textual changes are needed. The current set up allows each Ledger action to either use the generic component if sufficient, or a bespoke component if necessary.

Todo:

• Install @zondax/ledger-stacks when published
• Awaiting release of stacks.js package fix(encryption): change message signing prefix hirosystems/stacks.js#1329

Made a first pass through, looks like some good improvements while adding the message signing flow. 👍 I saw you moved the routes in with the feature which is interesting.

Maybe it never broke the lines on that screen? It does on the details screen before so was thinking it did.

Thanks for the feedback @fbwoolf—sorry totally forgot that we're also waiting on these changes in Stacks.js hirosystems/stacks.js#1329

Signature with long message is successful, but doesn't close the popup on success.

Fixed, had it not closing for debugging purposes

This is safe to merge, as it won't change existing behaviour
