Method record_process_for_tenant

nodedb/src/event/metrics.rs:88–101

Record event processing for a specific tenant. Also increments the global `events_processed` counter and updates LSN/sequence tracking. Silently skips tenant tracking if the per-core tenant map is full (bounded to `MAX_TRACKED_TENANTS`).
