Replace ChartsPackage with native Swift Charts

- Rewrite HeaderStatsView using SwiftUI Charts framework
- Delete unused GraphView.swift (only used in previews)
- Remove unused `import Charts` from DayView.swift
- Remove ChartsPackage SPM dependency from project
- Native Swift Charts is simpler and has no external dependencies
