fix: make sure weather direction to animate the shortest path

[tariknz]

Closes #39

[Copilot]

Pull Request Overview

This PR ensures the wind arrow always rotates along the shortest path, adds a metric/imperial toggle for wind speed, and tweaks container sizing in standings components.

• Implemented angle normalization in WindDirection to animate via the minimal rotation delta
• Added a metric prop (km/h vs mph) controlled by telemetry and updated speed formatting
• Removed full-height styling from Standings and Relative components

• Add unit tests covering angle normalization logic, especially around the ±π boundaries, to ensure the shortest-path calculation behaves correctly in all edge cases.
