fix: frontend bugs relating to redirects/tenants (#25)

* fix: frontend bugs

- Adds a query param `tenant` to application routes
- Allows setting an environment variable `SERVER_AUTH_SET_EMAIL_VERIFIED` to true which automatically sets the email to verified for new signups, since most local installations won't have an email verification mechanism
- When a user is logged in, navigating to `/auth/login` or `/auth/register` will redirect to the application via the no-auth.tsx middleware
- When there are no events found, the backend will no longer respond with a `500`-level error, and will return 0 rows instead
