Align Android with iOS reference behavior

- Overview PDF: usable energy summary, cable length, power loss,
  usable energy rows (matching iOS tables)
- Analytics: align event names and properties with iOS
- Localize default component names and editor dialog labels
- Unit system default via device measurement system (API 28+)
- Preserve BOM/affiliate fields when editing batteries/chargers
