Vishnu Mohandas e798ac02c6 [server] Check in with paid customers (#6106) ...

## Description
Update the `subscriptions` table to store the time at which
subscriptions were upgraded (`upgraded_at`).

Reach out to customers who upgraded 7 days ago to make sure all is well.

/>

Store this information within `notification_history` so they are not
contacted again (in case of admin interventions).

> Note: We will not be back-filling data for existing subscriptions.

## Tests
- [x] Tested locally to make sure only customers who upgraded 7 days ago
were pinged.
