James Rich e3a78f1afe feat(environment): add 1-Wire multi-thermometer (DS18B20) display support 
Add charting, detail card display, and CSV export for up to 8 1-Wire
temperature sensor channels from the environment_metrics.one_wire_temperature
repeated field.

- EnvironmentMetricsState: ONE_WIRE_TEMP_1..8 enum entries with getOrNull()
  access (safely returns null when firmware does not populate the field)
- EnvironmentCharts: LEGEND_DATA_4 with per-channel labels and distinct colours
- CommonCharts: LegendData.labelOverride for per-instance legend labels
- EnvironmentMetrics: OneWireTemperatureDisplay composable in the detail card
- EnvironmentMetrics component: inline 1-Wire chip display with temp formatting
- MetricsViewModel: Fahrenheit conversion for one_wire_temperature in CSV export

No version gating needed — the proto field defaults to an empty list on older
firmware, so the UI elements are naturally hidden when no data is reported.

:feature:node

Overview

The :feature:node module handles node-centric features, including the node list, detailed node information, telemetry charts, and the compass.

Key Components

1. NodeListScreen

Displays all nodes currently known to the application.

2. NodeDetailScreen

Shows exhaustive details for a specific node, including hardware info, position history, and last heard status.

3. MetricsViewModel

Manages the retrieval and display of telemetry data (e.g., battery, SNR, environment metrics) using charts.

4. CompassViewModel

Provides a compass interface to show the relative direction and distance to other nodes.
