## Description
Resolves an issue where individual plan customers who cancel are not
correctly put down to the free plan.
To resolve this, we delete the subscription on the stripe subscription
delete webhook. Since the customerId is stored on the organisation they
can still access their old invoices.
## Description
Previously we assumed that there can only be 1 subscription per user.
However, that will soon no longer the case with the introduction of the
Teams subscription.
This PR will apply the required migrations to support multiple
subscriptions.
## Changes Made
- Updated the Prisma schema to allow for multiple `Subscriptions` per
`User`
- Added a Stripe `customerId` field to the `User` model
- Updated relevant billing sections to support multiple subscriptions
## Testing Performed
- Tested running the Prisma migration on a demo database created on the
main branch
Will require a lot of additional testing.
## Checklist
- [ ] I have tested these changes locally and they work as expected.
- [ ] I have added/updated tests that prove the effectiveness of these
changes.
- [X] I have followed the project's coding style guidelines.
## Additional Notes
Added the following custom SQL statement to the migration:
> DELETE FROM "Subscription" WHERE "planId" IS NULL OR "priceId" IS
NULL;
Prior to deployment this will require changes to Stripe products:
- Adding `type` meta attribute
