[143] Frontend: Add performance budget and bundle analysis in CI

[broda-spendy]

What changed

• CI: New job Bundle analysis & size budget runs after lint + test: production build with \ANALYZE=true\ (
  ollup-plugin-visualizer\ → \dist/stats.html), then \size-limit\ against \dist/assets/*.{js,css}\ (gzip). Treemap is uploaded as artifact \�undle-stats.
• Config: \rontend/.size-limit.json\ (2.4 MB gzip cap for combined JS/CSS assets), \pnpm run build:analyze\ and \pnpm run size\ scripts.
• Build unblock: Wire \PaymentDetailModal\ + row selection state in \PaymentHistory\ and drop unused \Clock\ import so \ sc -b\ succeeds (required for CI build).

How to verify

\\�ash
cd frontend
pnpm install --frozen-lockfile
pnpm run test
pnpm run build:analyze
pnpm run size
\\

Delivered (issue Navin-xmr#143 — Junirezz/navin-frontend)
CI & tooling
frontend/.size-limit.json — gzip budget for all dist/assets/.js + dist/assets/.css (currently 2.4 MB total; local run ~136 KB gzipped).
vite.config.ts (+ synced vite.config.js) — rollup-plugin-visualizer when ANALYZE=true, writes dist/stats.html (treemap).
package.json — scripts build:analyze and size; dev deps: rollup-plugin-visualizer, size-limit, @size-limit/file, cross-env; pnpm-lock.yaml updated.
.github/workflows/ci.yml — job bundle-budget: install → pnpm run build:analyze → pnpm run size → upload frontend/dist/stats.html as artifact bundle-stats (14 days).
Docs
frontend/README.md — short section on bundle analysis and budgets.
Build fixes (so tsc -b / CI build succeed)
PaymentHistory.tsx — import PaymentDetailModal, state selectedPayment / isModalOpen.
PaymentDetailModal.tsx — remove unused Clock import.
Verification (local)
pnpm run test — 47 tests passed.
pnpm run build:analyze + pnpm run size — succeeded.
