This PR fixes an issue where active user counts were being computed
across _all_ measures instead of the per-minute measures.
We now compute them using the tokens per minute measure, as we're
concerned with usage in recent minutes.

This PR fixes an issue where the active user count spanned individual
models.
We now track the active user counts on a per-model basis.
Release Notes:

This PR makes it so Zed staff can use a separate Anthropic API key for
the LLM service.
We also added an `is_staff` column to the `usages` table so that we can
exclude staff usage from the "active users" metrics that influence the
rate limits.
