Flag for fully verified users

Need to make sure that the Spotify API calls and the EMA texts are only being sent to users who have connected their Spotify account, and verified their phone number.

• Ensure Spotify only collected for Spotify connected users

• Ensure EMA only sent to users with phone verified

• Check regarding 'overall' flag that indicates both the above have been completed.

For now, this is working well enough. Removing it from first working version milestone - could be an enhancement for a later version.
