fix: better run follow up issues

[doc-han]

Description

This PR currently fixes several issues around Better Run Experience

2. Making the primary action when a run is loaded to be "Retry" instead of "Create new workorder".

Closes #4736

[github-actions]

The PR is purely frontend: it moves a Ctrl/Cmd+Enter keyboard shortcut from WorkflowEditor.tsx into Header.tsx and reuses the existing handleRunClick callback (already gated by canRun and other UI conditions). No backend, query, policy, or audit-trail changes.

Security Review ✅

• S0 (project scoping): N/A — pure React/TSX change, no new queries or web-layer entrypoints touching project-scoped data.
• S1 (authorization): N/A — no new handle_event/controller actions; the shortcut just invokes the existing handleRunClick already governed by useCanRun() and server-side checks.
• S2 (audit trail): N/A — no writes to config resources, no Ecto.Multi changes.
