Add a copilot toggle button next to Test Run in the workflow header and
a left-mounted panel that runs the copilot Fix flow (start fix, live
SSE progress log, approve_repair/run_verify/provide_testdata/publish/
undo/re_fix actions, and a message box), auto-resolving the app id
(workflow store `appId`), workspace id (`currentWorkspaceAtom`), and
the most recent failed run (`useWorkflowRunHistory`) instead of
requiring manual entry.
Extracts the session/SSE request logic from the standalone
`/workflow-copilot-debug` page into a shared
`app/components/workflow-copilot` module (`use-copilot-session`) so
both the debug page and the new panel drive the same implementation.
Adds a `showWorkflowCopilotPanel` store flag (defaults false) mirroring
the existing `showEnvPanel` pattern, so the feature is fully additive
and does not affect rag-pipeline/snippet editors that reuse the same
header/panel shell.
