[sdc] SDC version 1.4.1 release

[gnanirahulnutakki]

SDC Helm Chart v1.4.1

Bump SDC Helm chart to version 1.4.1 to align with the new SDC server release.

Changes

• charts/sdc/Chart.yaml: version 1.4.0 → 1.4.1
• charts/sdc/Chart.yaml: appVersion 1.4.0 → 1.4.1

The container image tag defaults to the chart appVersion, so no values.yaml change is required.

Docker Image

docker pull radiantone/sdc-server:1.4.1

Release Notes

• SDC Server v1.4.1
• Compatibility details in the SDC-Server and SDC-Client Versions Compatibility - v8 Agents Confluence doc

Release Process

Once merged to master, chart-releaser-action will automatically:

1. Package the chart as sdc-1.4.1.tgz
2. Create GitHub release / tag sdc-1.4.1
3. Update the gh-pages Helm repo index

Stacked on #103 (1.4.0). This PR is based on the sdc/1.4.0 branch so the diff shows only the 1.4.0 → 1.4.1 bump. Merge 1.4.0 (#103) first; once its branch is deleted GitHub auto-retargets this PR to master, then this can be merged to cut sdc-1.4.1.
