element maintenance_ui_ux: filter notification-panel empty-state [Pinecone]/[Dendrite] as environment-invalid P2P

0 passes across 31 trials / 116 executions in the evaluation container
generation (deterministic 120s timeout on the labs-flag-gated Notifications
button, identical on near-baseline agent code; stable 3/3 in the capture
environment). Audit 2026-07-17, element panel flaky verification; pre-change
filter_list backed up under reeval/element_rightpanel_20260717/.
