Handle Phone sync with Store credentials data

[ThomazFB]

When the user opens the WearOS app, we should be able to start a sync with the user's phone to fetch the Store Credentials.

This task should introduce wear and phone connection detection, and transfer the credential data.

### Tasks
- [x] Create the connection service to detect Watch presence in the Woo phone app
- [x] Create the connection service to detect Phone presence in the Woo watch app
- [x] Trigger the credentials transfer from Phone to Watch
- [x] Safely store the credentials data into the Watch app
