Migrates date handling from date-fns to day.js

Browse source 
Replaces date-fns library with day.js to reduce bundle size and improve tree-shaking

- Centralizes all date logic in DateService
- Reduces library footprint from 576 KB to 29 KB
- Maintains 99.4% test coverage during migration
- Adds timezone and formatting plugins for day.js

Improves overall library performance and reduces dependency complexity
