Add a single info log line in each authn middleware once an identity is
resolved, so every authenticated request emits a record that ties the
request back to its user and credential:
- Cookie session middleware logs "session authenticated" with
identity_id and session_id.
- API key middleware logs "api key authenticated" with identity_id and
api_key_id.
- OAuth2 access token middleware logs "access token authenticated"
with identity_id and access_token_id.
The credential IDs are row identifiers (GIDs), not the secret token
values, so they're safe to log and let operators correlate a request
back to the specific credential used. The log lines use the
request-scoped logger from httpserver.LoggerFromContext so they
inherit http_request_id and any other middleware-attached attributes.
