Subject: [PATCH] Scale analytics stack to 0 replicas

The parca-analytics Prometheus, thanos-query, thanos-store and the
oauth2-proxy that fronts analytics.parca.dev are being scaled to zero.
Analytics ingestion has effectively been down anyway (it shares the
single, wedged ingress-nginx controller), so this removes its footprint
to verify the demo runs healthily without it while we evaluate moving
the analytics stack onto its own cluster.

PVCs, services, the Prometheus CR and object storage are retained --
only the pods stop -- so this is fully reversible by restoring the
replica counts.
