chore(attestations): Include attestation links on att push

[javirln]

This PR adds the ability to display a clickable link to view attestations in the platform UI after a successful attestation push command.

Helm Chart:

• Added uiDashboardUrl configuration field to values.yaml for operators to set the platform UI URL
• Updated configmap template to inject the platform URL into the control plane bootstrap configuration

CLI:

• Added logic to fetch the platform URL from the control plane's /infoz endpoint
• Display attestation view link after successful push in the format: https://example.com/attestation/{digest}?tab=summary
• Link only appears in table output format (not JSON/YAML) and is hidden in dry-run mode
• Displays the attestation url on attestation status and workflow workflow-run describe commands

Configuration

Operators can enable this feature by setting the platform URL in Helm values:

controlplane:
  uiDashboardURL: "https://example.com"

When configured, users will see the attestation link immediately after pushing, even if policy violations occur.

Examples:

See my comments, basically

• rename platform references for uiDashboard or similar, in other words, describe the actual component
• add the link in attestation status and describe outputs :)
