Add duty cycle/utilization fields, wheel picker for goals, and updated screenshots

- Add dutyCyclePercent and defaultUtilizationFactorPercent to ComponentLibraryItem
  with normalization logic and backend field fetching
- Change default dailyUsageHours from 1h to 24h
- Replace goal editor stepper with day/hour/minute wheel pickers
- Update app icon colors and remove duplicate icon assets
- Move SavedBattery.swift into Batteries/ directory, remove Pods group
- Add iPad-only flag and start frame support to screenshot framing scripts
- Rework localized App Store screenshot titles across all languages
- Add runtime goals and BOM completed items to sample data
- Bump version to 1.5.1 (build 41)
