Device Watch 1.0.6

• Today's mobile and Wi-Fi data usage is shown in megabytes when under 1 GB, so small real usage no longer looks like a stuck "0.0 GB".
• New widget layout: a 2x2 metric grid plus a full-width Wi-Fi row with network name, band, link speeds and today's usage. Grid rows now share the height equally, so the bottom of the widget can no longer get clipped. The battery health tile was removed (battery details remain in the app).
• The screensaver clock follows the device's 12/24-hour setting and shows an AM/PM marker in 12-hour mode.
