Multiple issues how am I supposed to use this?

### What happened?

1. Tried "latest", realized most of the endpoints are totally broken (i cant delete a collection or list it for example)
2. Attempt to use the dev version which is actually the latest, then realize that while v1 is merely deprecated, you cant even use it. Ok fine, we will try v2
3. Unable to list tenants, its just not an endpoint, like list db or list collections

How am I supposed to use this?

### Versions

"latest" as of March 7th, both dev and the docker latest. I'm not getting an actual version for you because this issue is still unresolved.

### Relevant log output

```shell

```

Start by reproducing the reported behavior with the latest and dev Docker images, checking collection listing, collection deletion, and tenant listing in both v1 and v2. Compare the available endpoints with the intended API behavior; done means these operations are usable or their supported alternatives are clearly documented.
