Bump firewall image to 2.1.0 (Helm + CloudFormation)

[Eric Hibbs (flowstate)]

Bumps the pinned firewall image from 2.0.14 to 2.1.0, and the chart version from 0.11.1 to 0.11.2, across the Helm chart and the CloudFormation templates and example values (same six files touched by #21).

Changes

• helm/Chart.yaml: appVersion 2.0.14 → 2.1.0, version 0.11.1 → 0.11.2
• helm/values.yaml: image.tag 2.0.14 → 2.1.0
• helm/README.md: values table default 2.0.14 → 2.1.0
• cloudformation/firewall-eks.yaml: FirewallImageTag default 2.0.14 → 2.1.0, ChartVersion default 0.11.1 → 0.11.2
• cloudformation/values/dns-override.values.yaml: image.tag 2.0.14 → 2.1.0
• cloudformation/README.md: two doc references to the defaults above

socketdev/socket-registry-firewall:2.1.0 is published on Docker Hub (upstream release workflow run 31233746194 succeeded).

Note

Low Risk
Version-pin and documentation-only changes with no application or infrastructure logic modified.

Overview
Bumps the pinned Socket Registry Firewall container image from 2.0.14 to 2.1.0 and the Helm chart from 0.11.1 to 0.11.2 so Helm installs and the AWS EKS CloudFormation handoff stay aligned on the same defaults.

In Helm, Chart.yaml updates appVersion and version; values.yaml and helm/README.md update the documented/default image.tag. In CloudFormation, firewall-eks.yaml defaults for FirewallImageTag and ChartVersion change; values/dns-override.values.yaml and cloudformation/README.md match those pins. No runtime logic or template behavior changes—only version strings and docs.
