feat(ui): add dual-core task monitor in status bar and CPU info in device screen

[r13xr13]

Summary

Two additions for visibility into the device runtime state:

Live core task counts in status bar — drawDualCoreInfo() displays C0:N C1:N on the status bar, updated on each frame draw. Shows how many FreeRTOS tasks are running on each core at any moment.

CPU info in device screen — Device info now shows chip model, revision, core count, frequency, and core affinity breakdown (which tasks run on which core).

Changes

• display.cpp: Add drawDualCoreInfo() function called from status bar
• utils.cpp: Add CPU section in showDeviceInfo() with model/rev/cores/freq/affinity

Testing

• Verified counts update in real time as tasks are created/destroyed
• Works on single-core (C5) and dual-core (all Xtensa) configurations
• Minimal overhead — uxTaskGetSystemState() call per frame draw

Have you tried this on a real physical device with a small screen?

I can almost guarantee it will look messy. The idea is good but has a big flaw...uses precious resources and redraw way too often.

Ok I stand corrected. Looks ok.
