This PR reworks our existing billing code in preparation for charging
based on LLM usage.
We aren't yet exercising the new billing-related code outside of
development.
There are some noteworthy changes for our existing LLM usage tracking:
- A new `monthly_usages` table has been added for tracking usage
per-user, per-model, per-month
- The per-month usage measures have been removed, in favor of the
`monthly_usages` table
- All of the per-month metrics in the Clickhouse rows have been changed
from a rolling 30-day window to a calendar month

This PR drops the `cache_creation_input_tokens_this_month ` and
`cache_read_input_tokens_this_month ` columns from the `usages` table in
the LLM database.
We mistakenly added these in #18834, but these aren't necessary due to
the structure of the `usages` table. We weren't actually using these
columns anywhere.

This PR extends the LLM usage tracking to support tracking usage for
cache writes and reads for Anthropic models.

This PR adds the ability to revoke access tokens for the LLM service.
There is a new `revoked_access_tokens` table that contains the
identifiers (`jti`) of revoked access tokens.
To revoke an access token, insert a record into this table:
```sql
insert into revoked_access_tokens (jti) values ('1e887b9e-37f5-49e8-8feb-3274e5a86b67');
```
We now attach the `jti` as `authn.jti` to the tracing spans so that we
can associate an access token with a given request to the LLM service.

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.

This PR puts the initial infrastructure for the LLM service's database
in place.
The LLM service will be using a separate Postgres database, with its own
set of migrations.
Currently we only connect to the database in development, as we don't
yet have the database setup for the staging/production environments.
