Night quality tracking

[plahteenlahti]

This task is about creating a better mood tracking feature in Nyxo Mobile. Using the current feature I would like the new one to work this way:

Basic mood tracking up to 30 days

When the user is not registered they can mark rating for the last 30 days, using the current rating system. Changes required:

• Show the rating under the day in top calendar strip with a small icon
• Add night rating into the sleep trend chart
• Add rating data to separate redux state

When the user has account

• Can save for many days
• Data is uploaded to the cloud
