feat(tauri): Initialize Context in background (#59)

This PR does the following:
- The Context (including Bitcoin wallet, Monero wallet, ...) is initialized in the background. This allows the window to be displayed instantly upon startup.
- Host sends events to Guest about progress of Context initialization. Those events are used to display an alert in the navigation bar.
- If a Tauri command is invoked which requires the Context to be available, an error will be returned
- As soon as the Context becomes available the `Guest` requests the history and Bitcoin balance
- Re-enables Material UI animations
