feat: add enterprise billing (#939)

## Description

Add support for enterprise billing plans.

Enterprise billing plans by default get access to everything early
adopters do:
- Unlimited teams
- Unlimited documents

They will also get additional features in the future.

## Notes

Pending webhook updates to support enterprise onboarding.
Rolled back env changes `NEXT_PUBLIC_PROJECT` since it doesn't seem to
work.
