fix: remove bignumber from the redux store

[victorkirov]

🔘 PR Type

What kind of change does this PR introduce?

• Bugfix

📜 Background

When changing settings, if you have multiple tabs open, the saved settings are overwritten by the last tab that is closed, and settings are not propagated across tabs. This is due to the store sync not syncing everything, which was disabled because we had class instances in the store.

🔄 Changes

All BigNumber instances were removed from the store and the values were cast to BigNumber where needed throughout the code. A number of other components were also changed to fix any linting and typing issues that were blocking commits.

Impact:

• This changes stx and btc balances and fiat rates in the store, so it would affect any component which uses those
• Since we updated the store sync, this will also affect onboarding and the data that was synced between tabs during onboarding
