Add `vite-bundle-visualizer` and reduce bundle size

[ritik4ever]

Problem

There is no visibility into what's inflating the frontend bundle. Hidden large dependencies may slow the initial load.

Scope

Run bundle analysis, identify top contributors, and optimize.

Acceptance criteria

• npm run build:analyze generates the bundle visualization
• Top 3 largest chunks identified and code-split or replaced
• Gzipped bundle size documented in frontend/PERFORMANCE.md
• React Router lazy-loading applied for page-level routes
