Precise USB 3 speed on Apple Silicon front USB-C ports

What's fixed

Devices on front USB-C ports now show their precise USB 3 speed (issue #190 follow-up). On Mac Studio (and Apple Silicon in general), the front USB-C ports route through an internal Apple chip that adds an extra hop to IOKit's locationID field. WhatCable was using locationID to decide which USB device on a port is "directly attached", so a directly-plugged device on a front port looked (to that check) like it was behind a hub. The port summary then dropped the device's speed and showed the generic "SuperSpeed USB (5 Gbps or faster)" fallback. The check now uses the IOKit driver's port-name correlation, which is unaffected by the internal hop. iPhone 17 Pro or any other SuperSpeed device on a front USB-C port reads "USB 3.2 Gen 2 (10 Gbps)" again, matching what the Devices section below already says. Thanks @i0ntempest for spotting it on a Mac Studio M4 Max.
Pro Pin Diagram applies the same fix. The pin overlay reads USB 3 speed from the same path the port summary now corrects, so the diagram and the summary agree on every port.

"Alt Mode" capitalised consistently across every language. Was written as "alt mode" / "Alt mode" / "ALT mode" in different locales. Now uniformly "Alt Mode" (or the closest cap convention in each language's preferred orthography).
