chore: implement vendor chunk splitting for production builds

Add strategic code splitting to reduce main bundle size from 11MB to 3.7MB
(66% reduction) and improve browser caching efficiency.

Changes:
- Add splitChunks configuration with vendor cache groups:
  * vendors-react: React, Redux, Router (~168KB)
  * vendors-antd: Ant Design core (~1.6MB)
  * vendors-antd-icons: Ant Design icons (~150KB)
  * vendors-charts: Chart libraries (~264KB)
  * vendors-react-query: React Query (~47KB)
  * vendors-signozhq: SigNoz UI components (~338KB)
  * vendors-utilities: lodash-es, dnd-kit, dayjs, axios, i18next (~198KB)
  * vendors-monaco: Monaco editor (~11KB)
  * vendors-common: Other shared dependencies (~1.2MB)
- Enable module concatenation for better tree-shaking
- Update bundlesize.config.json with granular limits per chunk type
- Restrict window.store exposure to development only

Performance Impact:
- Main bundle: 11MB → 3.7MB (66% reduction)
- Total build: 250MB → 97MB (61% reduction)
- Better browser caching (vendor chunks change less frequently)
- Faster subsequent page loads (cached vendor chunks)

Breaking Changes: None
Migration: None required
