chore(deps): address esbuild audit advisory / 修复 esbuild 审计告警

[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

Supersession note: #3693 raised the automated Vite 8.0.16 dependency bump, and this PR is the human migration path for the same esbuild/Vite audit work, including the config and lockfile migration that the automated bump could not complete. Thank you @dependabot for opening the tracking update in #3693.

Authorship note: @SivanCola is the primary author of this PR. @dependabot contributed as repository automation by opening the original dependency bump that identified the update target, and that contribution is acknowledged as part of the shared repository cleanup.
