Say what caused a value, and draw what is not a node

Moving a dashboard slider lit up an edge between two nodes that had done
nothing. The canvas pulsed on the message's timestamp alone, and a message
has no idea who published it — so it credited whichever node happened to
be drawn as a producer.

That was never only about dashboards. Two nodes producing one message
pulsed both their edges whichever fired, and a message produced in another
flow changed with nothing on screen to account for it at all.

Values now carry their cause: a node, a dashboard widget, another flow, an
agent or an API caller. An edge pulses only for the producer that actually
published, and the edge inspector says where a value came from when it did
not come from a node.

What is not a node in this flow is now drawn as one — a label rather than
a card, because a dashboard with twenty tiles would otherwise bury the
logic the canvas exists to show. That covers cross-flow wiring too, which
is the link in/out affordance that has been missing.

They are never part of the document. They join at render, after everything
that reads or writes the canvas nodes, so an autosave, an undo or a delete
cannot reach them — with a Playwright test that drags a node and asserts
the stored flow still holds exactly what it did.

## Open
- FEAT/UX: unify the layout between dashboard and flows: 1) In the flows: adapt the "overview" from the dashboard; clicking flows in the sidebar leads to a searchable overview of flows like in the dashboard. Then the "flowbar" get's merged into the bottom toolbar (status and edit button; add flow button goes in the overview) with the name of the current flow still being displayed at the top for reference. 2) adopt the floating bottom toolbar from the flow viewport and the click widget to edit behavior (make sure inputs like sliders and buttons stay interactable). Also adapt the new flow-title (sync UI) and the new edit button in the toolbar to trigger a panel for renaming the flow (and more later). The same floating right panel as in the flows should also be the way to go to edit a widget. Then in the toolbar should be a "View" button which opens the dashboard in a new browser tab (renders without the sidebar or any edit option) with a link to be used in a wallpanel later
- FEAT/UI: allow resizing of dashboard widgets by dragging edges and add the same dotted background we see in the flows viewport (again, sync UI (see above))
- FEAT/UI: add a graph widget to the dashboard
- BUG/UI: strictly type a dashboard widget; i.e. wiring a boolean switch to a float message (or wiring no publish/consume at all) should flag the node as error -> reuse error indicator from the flows
- FEAt/UX: allow setting a grid size for the dashboard to adjust to different wallpanel sizes (goes into the new dashboard panel setting; see above)
- FEAT/UX: allow copy-pasting of nodes (also between flows)
- FEAT/UX: introduce general keyboard shortcut system. As a first test: when hitting ctrl-s we should catch this keyboard shortcut to a) publish a flow b) save (and apply) code changes when in the code editor
- FEAT/UX: in delay and schedule nodes: help creating cron schedules by providing a legend; Also: if interval is entered, this should automatically create a cron according to the interval set
- FEAT/UX: python function should automatically update according to what the node consumes or produces
- BUG/UI: there are two places to rename a flow; we should only go for the one in the top of the panel name (so that the UX is identical to the ones from the nodes). The actual rename should happen with dedicated "confirm" button (same for the nodes)
- BUG/UI: when the edges pulse on message, they change their color (go from slightly darker back to normal) at the end again. Double check that after the animation they end up with the same color as before to not have this double-pulse effect
- BUG/UI: enlarge the icon in the sidebar slightly
- BUG/UI: clicking outside the panel does not discard the flow edit panel
- FEAT/UX: for the same type of node show suggestions in the setting fields based on other nodes; I.e. if I create an mqtt node and I already configured one in another flow, allow selecting the values of the exiting mqtt node as a drop-down option (identical to consumables) when clicking inside the corresponding field in the new node (same for all other nodes)
- BUG/UI: the graph showed in the node edit panel should also be shown for a specific edge inside the pop-up panel when clicking the edge
- FEAT/FLOW: single-stepping a paused flow. The work queue it needed now exists: pausing
parks claimed items per flow and resuming drains them, so a step button is a matter of

mode bits hold a value outside the known set. Faithful to the reference decoder, but
"off" would read better.
- FEAT/UI: an endpoint's edge routes straight across the graph, so it can pass behind a
node that sits between the lane and the node it wires to. Readable, but a routed edge
would be tidier.
- FEAT/UI: endpoints are always shown. A flow read by a twenty-tile wall panel gets twenty
labels, and only the input ones affect the graph — dimming or collapsing consumers is
the obvious next move if it turns out busy.
