Several compounding freeze sources in plugins/motion_capture/:
- tracker.py: _run_real had no frame-rate cap independent of the camera's
configured fps (up to 120fps/2560x1440 was possible), and no bound on
consecutive failed reads — a camera that "opens" (cv2 isOpened() can lie,
seen with Windows MSMF/obsensor) but never actually delivers frames would
get hammered forever. Added a 20Hz processing cap, a real test-read before
committing to a camera, and a give-up-after-30-failures fallback to
simulation.
- tracker.py/device.py: cv2.VideoCapture() opening a real camera is a slow,
blocking call — CameraTracker.start() used to do this synchronously on
the caller's thread, which froze the whole app when ProfileManager.apply()
called it during profile load. Now runs on the background thread; status
reporting (CameraDevice) moved to an on_result callback since the caller
can no longer learn the outcome synchronously.
- window.py: the Camera View preview ran a 30Hz GUI-thread timer doing a
full-frame copy + QImage/QPixmap rebuild every tick unconditionally (no
visibility check) — dropped to 10Hz and skips entirely when hidden.
Camera enumeration (list_cameras(), up to 8 sequential cv2.VideoCapture
probes) also ran inline in the window constructor, blocking it open the
same way camera_panel.py's CameraScanThread already avoided for the Add
Device dialog — moved to the same async pattern here.
config_window.py: separately, ConfigWindow._dev_poll (device status label
refresh) was stopped in closeEvent and never restarted, since MainWindow
reuses the same ConfigWindow instance across opens — invisible before
because connect() was synchronous, but with the above change a device can
sit in CONNECTING for a while, and a stale poll made that look stuck
forever after reopening the window. Restart it in showEvent.

Channel ID renames
Generalized the Plot pane drag-to-reorder (_PaneDragHandle/_PlotDropContainer
-> _DragHandle/_DragReorderContainer) and reused it for the Channels tab's
derived-channel list; reordering also updates SignalProcessor's evaluation
order (list order matters for chained Channels) via new reorder_derived().
Namespace panel: added an ID column (bare channel_id, matching the actual
channels.get(...) script convention) and fixed the Source column for
Channels to show resolved absolute references (dev_id/ch_id for a Signal,
bare id for a chained Channel) instead of the operation kind, so a chain
is traceable by eye.
Fixed a real bug this surfaced: renaming a Channel's ID never propagated
to other Channels' sources, leaving dangling ("derived", old_id)
references that silently stopped updating. Added
SignalProcessor.rename_derived() to fix up sources plus carry the ring
buffer/latest-value cache to the new key, wired to DerivedBlock's Apply.

Devices tab split into Physical Devices (left) / Signals (right); Channels
tab now hosts the Namespace browser (left) alongside Channels (right,
larger by default). Plot Builder panes gain drag-to-reorder (same mechanics
as ControlPanel's widget list, adapted for the editable pane title via a
dedicated grip icon), "+ Add Channel" moved beside Size for a more compact
row, and Min/Max/Size/line-width spin boxes widened so values no longer
overlap the up/down arrows.

- Split device tab into pysical devices and signals.
- Replaced old Signals panel (under Channels tab) with namespace.
to make Channel creation easier.

Devices: auto-name from OS-reported port description (Device Manager /
udev string) instead of a generic label; default Serial #Channels 1;
consistent simulate-mode checkbox across backends; inline device rename.
Channels: calibration/filters move out of Signals into a Channel
"Operation" (adds Scale/Offset alongside the existing math kinds);
single-physical-source Channels get an embedded Filters block; new
Channels auto-name/auto-ID from their source and reject duplicate
names/IDs on apply; "Create Channel" button on each Signal row; renamed
"Sources" -> "Signals" in the Channels UI; Signals' READ/WRITE dir badge
(was silently-broken IN/OUT) now reflects the real writable flag.
Plot: default layout is one pane per Channel (not per device, not raw
Signals) titled by channel name; "+ Add Channel" is a checkbox dialog
instead of an inline dropdown; traces get up/down reorder; live unit
changes (e.g. a Mark-10 gauge switching lb/kgF/N/ozF) propagate to an
open pane's axis label without clobbering a manually-typed one.
Control Panel: hardware assignment now picks from the same writable-
Signals list instead of a separate device/channel combo with a
hardcoded Arduino pin list; stale visual indicator when a control's
target device/channel disconnects or disappears; documented the `vars`
bridge (Control Panel On Action Script <-> Channel scripts) in both
directions' help text and script templates.

Replaces three separate floating windows with single tabbed ConfigWindow:
- Tab 0: Devices (device cards, add/remove/configure)
- Tab 1: Channels (signal table with Dir/IN/OUT badge + pipeline ⚙ per row; derived channels pane)
- Tab 2: Plot (layout canvas + pane config)
Adds is_output field to ChannelConfig for output channel direction badges.
