Weekly emails receipt history

[epipav]

Changes proposed ✍️

• Cubejs queries were not hitting the cache because we were sending the custom date ranges in seconds granularity.
• Now we're sending the queries with day granularity (without the hour part) so that cubejs catches these queries with daily-gran preaggregation tables
• Introducing weeklyAnalyticsEmailsHistory table, where we keep all email receipts for weekly analytics. We keep track of emailSentAt emailSentTo and weekOfYear.
• Introducing a convenience script that makes it easier for us to send a weekly email to a specific tenant. This script also checks if the email is already sent, and if it's it won't send the email.
• After merging this, I'll run the convenience script for tenants that didn't receive an email this week.
