Complete the NetworkPolicy egress guidance (MaxMind, FQDN example, sidecar note)

Description

The values.yaml egress comment (deploy/helm/tailscale2otel/values.yaml:484-505) lists API/OTLP/S3 destinations but omits the MaxMind download endpoint used by enrichment.geoip.download - a fourth silent-failure egress under allowAll: false. Add it, plus a worked Cilium/Calico FQDN example and a note on extraContainers sidecar grace-period ordering vs the 45s staged shutdown (values.yaml:173-215). Regenerate the chart README.

Acceptance Criteria

Definition of Done

Implementation Plan

Lane K adds MaxMind egress, FQDN-policy examples, and sidecar shutdown-order guidance, then regenerates the Helm README.

Implementation Notes

Lane K documented MaxMind egress, worked Cilium/Calico FQDN policies, and sidecar shutdown ordering, then regenerated the Helm README. Helm lint/template and drift checks passed; code tests were intentionally skipped for documentation/declarative config.

Required CodeRabbit pre-commit review attempted on the integrated staged diff after just check passed; the service failed before analysis with recoverable and emitted no line. Treated as a failed review, not a clean result. Root manually reviewed the full staged diff and found no blocking issue; this is an overnight review-service deviation.

Correction to the preceding note: the exact recoverable error was WebSocket closed, and the review emitted no complete status line.

Final Summary

Documented MaxMind egress, Cilium and Calico FQDN policy examples, and sidecar shutdown ordering, then regenerated and verified Helm documentation. Implementation SHA d3af40f. Final integrated just check passed at 5b55617; exact-head CI run 33354208183 completed success.
