List all alert rules for the specified tenant.

Returns rules of all condition types and statuses, including subscriber configuration. Each rule's event history is omitted unless includeEvents=true is passed, because it is read separately and can be large on a long-lived tenant.

Tenant lookup requires READ_ALERT_RULES, including when embedding events. The separate rule-events endpoint requires READ_ALERT_RULE_EVENTS. With reportID supplied, the report-specific lookup ignores includeEvents.
