Remove unused response bodies from a number of API endpoints.

This removes the response body from the following methods:

* `POST /api/setup`
* `POST /api/auth/login`
* `POST /api/invite/:id`
* `POST /api/password`

The bodies returned from these methods were something of a rough guess as to what might be useful. Actual client development has shown that we don't use _any_ of the data from any of these API responses, so let's not tie ourselves to future compatibility by continuing to send them. We can add a body to a bodyless method a _lot_ more easily than we can change the body of a method that already returns one, after all.

These changes are not backwards compatible for clients which care about the existing bodies. To my knowledge, there are no such clients; the included client definitely doesn't care.

## Internals

Not only does this change stop returning bodies at the API surface, but it also stops retrieving and returning values used internally to construct those responses, simplifying the code a bit in the process.

One side effect of this is that tests that need to log in a user now need to manually verify the returned token secret, to convert it back into a user, whereas the previous versions returned both a token secret and a user during password login. I don't love the increase in the size of the tests, but I think it's the right tradeoff (and this change is code net-negative anyways).

Merges no-content into main.
