chore(deps): address esbuild audit advisory

[SivanCola]

Summary

• upgrade desktop frontend Vite to 8.0.16 so the build toolchain resolves esbuild 0.28.1
• remove the stale esbuild ^0.25.0 overrides from npm/pnpm configuration
• migrate Vite manual chunk config to Vite 8/Rolldown codeSplitting groups

Verification

• pnpm --dir desktop/frontend install --frozen-lockfile
• cd desktop && wails generate module
• pnpm --dir frontend build
• pnpm --dir frontend test
• npm audit --audit-level=high
• pnpm audit --audit-level high
• npm ci --ignore-scripts
