Copy nodes, bind the keys, and keep publish within reach

The floating bars used to make way for a side panel, which hid Publish
exactly when a node had just been edited. They keep their lane now and
the panel is inset out of it; the enlarged code editor stays a floating
surface between the two bars rather than covering them.

Shortcuts are one small registry (`lib/shortcuts.ts`): undo, redo, ⌘K,
copy, paste, and ⌘S — which publishes the flow, or applies the code when
the editor has focus. Copying carries a node's own source through
localStorage, so a paste works in another flow too.

A flow is now named where a node is, at the top of its panel and only
there, and both take effect on Confirm. Flow-level edits go through the
undo stack with everything else, clicking the canvas puts the flow panel
away, a failing node opens the logs filtered to its own traceback, and
the panel carries its test id on a phone as well.
