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

`embedded-io-async`

Async IO traits for embedded systems.

This crate contains asynchronous versions of the embedded-io traits and shares its scope and design goals.

This project is developed and maintained by the HAL team.

Optional Cargo features

std: Adds From impls to convert to/from std::io structs, adds std::error::Error impls.
alloc: Adds blanket impls for Box, adds Write impl to Vec.
defmt-03: Derive defmt::Format from defmt 0.3 for enums and structs.

Minimum Supported Rust Version (MSRV)

This crate requires Rust nightly newer than nightly-2022-11-22, due to requiring support for async fn in traits (AFIT), which is not stable yet.

Keep in mind Rust nightlies can make backwards-incompatible changes to unstable features at any time.
