Source-level cleanup with no behavior changes:
- Drop unused React default imports (React 19 auto JSX runtime)
- Hoist CHART_COLORS and add MAX_DOTS_DAYS / MAX_LEGEND_LINES named constants
- Use date-fns addDays/subDays in route helpers (no more setDate mutation)
- Drop dead current:0 field from progress state
- Use format() for export filename (local tz, not UTC)
- Replace key={idx} with composite domain keys in table rows
- Fix border-3 (non-existent in Tailwind v4) -> border-[3px] in spinner
- Fix html lang from "vi" to "en" to match UI language
- Sync description text to "Excel or CSV" across metadata and header
Restructure:
- Rename ExchangeRateViewer.js -> exchange-rate-viewer.js (kebab-case)
- Extract icons, storage helpers, and constants into sibling modules
