New frontend websocket config

[amaloney1]

Pull Request Template

What?

Removed old frontend websocket configs (per-node) and replaced it with the name style pipeline (single, ordered pipeline). Enforced some order based on workflow document.

---

How?

Websocket config:

• Built a PipelinePayload from the React Flow graph using topological sorting for execution order.
• Added defaults for preprocessing and window configs
• Moved node config handling so that filter/window nodes push config into their node data rather than dispatching global events (pipeline is therefore built directly from graph state)
• Replaced per-config websocket messages with a single pipeline payload send (on pipeline changes and websocket open)

Workflow enforcement:

• Added validatePipeline to compute errors and warnings before sending the pipeline
• Enforced structural constraints including: only 1 source and window node, window must connect to source directly, output nodes are terminal, etc.
• added console warnings for ordering issues (e.g. filter before window)

---

Testing

Ran the local frontend to briefly test the order changes made. Feature/pipeline/backend tested the compatibility of the websocket change with the backend workflow.
