Refactor the app, fix bugs and add tests.

[overcat]

Note

• The Ledger App project started several years ago, and some things may seem outdated at the moment, so I refactored the app based on app-boilerplate.
• This is a large PR, so it may take more effort to review it, thank you for your efforts. 🙏
• While this update contains breaking changes, but it does not affect Ledger Live, StellarX, StellarTerm and Stellar Account Viewer, they still work well together.

Changelog

Updated

• Added a Sequence Number setting: Displayed or NOT Displayed, default to NOT Displayed. (resolves Sequence Number setting #40)
• Optimized the display of amount. (ex. 10000000 XLM -> 10,000,000 XLM) (resolves Use commas in amount formatting #39)
• Optimized the display of offer price.

@lpascal-ledger It looks like the CI run failed after the merge, let me check.

@lpascal-ledger Looks like the swap-ci-workflow.yml is outdated, I'll make a separate PR to fix this, please wait a moment.

@overcat I'm on it, don't worry. Bitcoin application cutoff some legacy last week so it's expected.
Also refreshing branch protection rules in the same time.

Nice CI though.

@lpascal-ledger I made a duplicate PR #45 since I didn't notice that you made a PR
