This is required to control the resource consumption in case of no
usage of wallet connect
Hence we load the WebEngineView only if we have active pairings and
such that SDK events are expected from the paired dapps.
Also:
- Moved the generic WebEngineView communication bridge to StatusQ
- Added basic tests for WebEngineLoader
- Add a way to know when wallet is loaded (`walletReady`)
- Add storybook support for mock of nim sections as context properties
