Fix total aggregate values

[EDsCODE]

Changes

Please describe.

• addresses Bug/UX issue with table views #2722
• currently when you use trends and select table or pie chart, it uses the count attribute that we return alongside trend data. This count value is a simple sum over the results in the trend aggregation. If there's a trend graph of active users that's on day interval, the count value will sum the aggregated values for each day but this will double count active users that appeared multiple days in the range. When a pie chart is used to visualize this same data, it will be showing this double counted value.

What's Left:

• Clickhouse aggregate value for breakdown query
• Aggregate value tests for breakdown
• Aggregate value for sessions related queries
• Frontend Logic swapover (from count to aggregated_value)

Checklist

• All querysets/queries filter by Organization, by Team, and by User
• Django backend tests
• Jest frontend tests
• Cypress end-to-end tests
