Add type: integer to OCSF facets in auth0

[daniel-trinh]

What does this PR do?

Adds type: integer to OCSF facet definitions for ocsf.activity_id, ocsf.category_uid, ocsf.class_uid, and ocsf.status_id in the auth0 log pipeline yaml.

Motivation

The validate-logs CI check fails when these facets are missing type: integer, as other integrations define them with that type. Fixes SEC-31840.
