* chore: add /v2 to import module path
go mod requires semantic versioning with versions greater than 1.x
This was a mechanical update by running:
```
go install github.com/marwan-at-work/mod/cmd/mod@latest
mod upgrade
```
Migrate generated files to import /v2
* Fix gen
* chore: Rbac errors should be returned, and not hidden behind 404
SqlErrNoRows was hiding actual errors
* Replace sql.ErrNoRow checks
* Remove sql err no rows check from dbauthz test
* Fix to use dbauthz system user
Customer feedback indicated projects was a confusing name.
After querying the team internally, it seemed unanimous
that it is indeed a confusing name.
Here's for a lil less confusion @ashmeer7 🥂
