Add Argo Rollouts documentation

[idan-codefresh]

Summary

• Adds new documentation section at /docs/kubernetes/argo-rollouts/ covering the upcoming Argo Rollouts visualization and control feature
• Includes an overview page and a dedicated control actions reference page
• Exports Figma design screenshots and includes them inline in the docs

Pages added

Overview (/docs/kubernetes/argo-rollouts/):

• What Octopus provides (visualization + control, not rollout authoring)
• Supported deployment paths: Kubernetes Agent and Argo CD Gateway
• Deployment behavior — Octopus waits for the rollout to complete before marking the step successful
• Project Dashboard rollout status (shown during deployment only)
• Rollouts popover
• Rollout Details Drawer
• Task Log integration
• RBAC summary

Control actions (/docs/kubernetes/argo-rollouts/control-actions):

• Full reference for all actions: Pause, Promote, Promote Full, Restart, Retry, Abort, Rollback
• State-based availability table (which actions are available in which rollout state)
• Permissions table and audit log behavior

Images

Screenshots exported from the 2026 - Rollouts Figma file:

• rollout-active-canary.png — active canary rollout with traffic split
• rollout-active-blue-green.png — active blue-green rollout
• rollout-paused.png — paused rollout state
• rollout-completed.png — successfully completed rollout
• rollout-degraded.png — degraded/failed rollout
• rollout-popover.png — rollout status popover (provided manually)
• rollout-details-drawer.png — Rollout Details Drawer (provided manually)

Test plan

• Run pnpm dev and verify both pages render correctly
• Check all images load and alt text is accurate
• Verify internal links resolve (/docs/kubernetes/live-object-status, /docs/argo-cd, /docs/kubernetes/targets/kubernetes-agent)
• Run pnpm spellcheck on the new files
