[artifactory] Add RTFS pod label values

[omribz156]

PR Checklist

• Chart Version bumped
• CHANGELOG.md updated
• Variables and other changes are documented in values.yaml
• Title of the PR starts with chart name (e.g. [artifactory])

What this PR does / why we need it:

Adds a shared rtfs.labels value for the Artifactory and Artifactory HA charts, and renders those labels on both the RTFS Deployment metadata and the RTFS pod template metadata.

rtfs.deployment.labels is preserved as a Deployment-only label override. The new rtfs.labels mirrors the existing chart pattern used by workloads such as Artifactory and NGINX where a single labels value is applied to both the controller object and pods.

Which issue this PR fixes (optional, in fixes #<issue number>(, fixes #<issue_number>, ...) format, will close that issue when PR gets merged): fixes #2309

Verification:

• git diff --check
• rg 'rtfs\.labels|Labels to add to the RTFS Deployment' -n stable\artifactory stable\artifactory-ha

I could not run helm template/make lint locally because this Windows workspace does not have helm, kubectl, or kubeval installed.

Special notes for your reviewer:

I left the chart version unchecked because there are active automated Artifactory release PRs in flight; happy to adjust the version bump if you prefer it in this PR.

This was implemented with Codex assistance, with the patch kept focused and manually reviewed.
