Title: Improve BinaryIO telemetry pipeline, controls, and logging UI (adds resizable graph & full PID controls)

[ecarjat]

@geekuillaume Fantastic work on this impressive app!

This PR for your consideration adds the performance and UX improvements described in BinaryIO_MIgration.md, Performance_Refactor.md, and LOG.md.

What changed

• Telemetry & rendering: Introduced a throttled, buffered TelemetryPipeline with Plotly streaming (extendTraces) and configurable downsampling/backpressure. The motor monitor graph supports dynamic Y1/Y2 assignment, a draggable resizable plot area, and grouped register selection (primary signals on top, Velocity/Angle PID in collapsible accordions).
• Serial/logging: BinaryIO now decodes log packets (L) per LOG.md, with toggles to show/hide telemetry/logs, freeze, decode, and auto-scroll controls in the serial viewer.
• Control panels: Control and PID sections use compact inline sliders with bounds dialogs; Angle PID now exposes all registers (P/I/D, ramp, limit, filter); Control accordion opens by default.
• UX polish: Motor avatar turns green when enabled (red otherwise) with deduped numeric labels; container layout widened; plot margins adjusted for axis visibility.

Spec highlights

• BinaryIO_MIgration.md: Dual-mode serial with BinaryIO support, register-mapped controls, binary telemetry parsing, and DSL/packet visibility.
• Performance_Refactor.md: Decoupled ingest/render with bounded buffers, render loop, streaming Plotly updates, and observability hooks.
• LOG.md: BinaryIO log packet handling with

level/tag/message decoding in the UI.

Testing

Verified on BinaryIO protocol (telemetry/logs/control). Not tested on ASCII Commander.

I realise this might be a bit much as a PR but there was a number of things I needed the interface to do. I you want to test it live, it lives here:
