swaitsandClaude Opus 4.6 3102fc747a feat: add display UI with splash screen, dashboard, and RSSI sparkline
Implement full SSD1306 OLED display support:
- Splash screen on boot (1.5s) with project name, version, board
- Dashboard showing radio state, config, counters, RSSI/SNR
- RSSI history sparkline (64-sample ring buffer, 2px-wide bars)
- DisplayOn/DisplayOff host commands routed via dedicated channel
- Pure render functions against generic DrawTarget (no hardware coupling)
- Display on/off control bypasses radio task entirely

//! # Inter-Integrated Circuit (I2C)

//! I2C is a serial, synchronous, multi-device, half-duplex communication
//! protocol that allows co-existence of multiple masters and slaves on the
//! same bus. I2C uses two bidirectional open-drain lines: serial data line
//! (SDA) and serial clock line (SCL), pulled up by resistors.
