rABCb612be7f9aec: [Cashtab] load wallet from storage before calling API

Reconfigure wallet loading and activation functions to pull directly from local storage (if present) before any API call

Includes unit test to make sure wallet page still loads correctly for users who have not yet opened Cashtab in recent enough version to save wallet.state to local storage. The wallet.state object retains some artefacts to support this edge case legacy user.

Note: some other features I considered adding in this diff but should have their own diff: disable notifications for incoming txs when user switches wallet, make user wallet selection a dropdown from the Wallet page

Test Plan

npm test to confirm new unit tests

npm start and observe wallet loads faster and does not flash incorrect balance before loading
Navigate to settings page and activate a different wallet. Observe activation is almost instant.
