chore(frontend): upgrade Vite to 8

[alainncls]

Summary

• Upgrade the explorer and tutorial Vite toolchains to Vite 8.0.10.
• Upgrade the React Vite plugin to v6 and vite-plugin-svgr to v5 where used.
• Remove vite-tsconfig-paths from the explorer config and use Vite 8 native resolve.tsconfigPaths instead.
• Add an explicit tutorial web3 chunk for the wallet stack so Rolldown does not split viem into a runtime cycle.

Impact

• Explorer and tutorial stay on Vite 8.
• The tutorial preview previously rendered a black screen because the production bundle split viem across a circular index <-> _esm chunk relationship, leaving BaseError undefined at module evaluation time.
• vite-plugin-radar remains on 0.10.1 because it is the latest available release. It builds with Vite 8, but its peer dependency range only declares Vite up to 7, so reviewers should keep that compatibility risk in mind.

Validation

• pnpm --filter verax-explorer run build
• pnpm --filter @verax-attestation-registry/verax-tutorial run build
• pnpm --filter verax-explorer run lint
• pnpm --filter @verax-attestation-registry/verax-tutorial run lint
• Headless Chrome against local vite preview: no Uncaught/TypeError/ReferenceError/SyntaxError, and the page renders Connect your wallet.
• Pre-commit hook: Prettier, full lint, Forge tests (199 tests passed). Solhint emitted existing import-path warnings only; no errors.

J'ai reproduit la preview noire sur le deploy Netlify : le bundle production lançait Uncaught TypeError: Class extends value undefined is not a constructor or null dans le chunk _esm-*.js généré à partir de viem/_esm.

Cause : avec Vite 8/Rolldown, le tutorial découpait la stack wallet/web3 en chunks circulaires. Le chunk viem importait BaseError depuis le chunk principal, pendant que le chunk principal importait déjà viem, donc BaseError était encore undefined à l'évaluation.

Fix poussé en 48ac290 : tutorial/vite.config.ts force seulement les packages web3/wallet (viem, wagmi, @reown, WalletConnect, etc.) dans un chunk web3, ce qui garde Vite 8 et évite le cycle runtime sans revenir à Vite 7.

Validé localement : build tutorial, lint tutorial, Prettier ciblé, git diff --check, pre-commit complet (dont Forge : 199 tests passés), et headless Chrome sur vite preview sans Uncaught/TypeError avec la page rendue (Connect your wallet).
