Current sketch path:

## Current Bring-Up Screen
The dashboard sketch now replaces the stock Waveshare LVGL demo with a simple Overland Controller boot/status screen.
Current screen shows:
- Overland Controller title
- Waveshare ESP32-S3 Touch LCD 5B hardware target
- 1024x600 display note
- `/api/v1` Cargo API base
- WiFi placeholder
- Touch test button
This is intentionally not connected to WiFi or the Cargo ESP yet.
