fix(fuzequality): cast the MF shared config so the frontend image type-checks

[izzywdev]

Regression from #701 — my bug

Adding singleton: true to FuzeQuality's Module-Federation shared config broke the frontend image build:

apps/web/vite.config.ts(30,18): error TS2322: Type '{ react: { singleton: true;
requiredVersion: string; }; ... }' is not assignable to type 'Shared | undefined'.

Root cause

Confirmed against the installed types, not guessed. In @originjs/vite-plugin-federation@1.4.1, SharedConfig.singleton is commented out of types/index.d.ts:

declare interface SharedConfig {
  requiredVersion?: string | false
  // singleton?: boolean      <-- declared only in a comment
}

So the object literal fails excess-property checking. The plugin honours singleton at runtime; only its type declaration omits it.

Fix

Mirror the host verbatim — frontend/vite.config.ts:187-188 already carries the identical as any cast for the identical reason, on the identical plugin version. Keeping the two byte-compatible is the entire point of that block: a mismatch lets the remote load its own React and die on "Invalid hook call" in the browser.

Verification

Compiled both forms against the real 1.4.1 type definitions:

form	result
without cast	TS2353: 'singleton' does not exist in type 'SharedConfig' — on both entries
with cast	clean

Why it matters

fuzequality-release.yml is still failing, so the FuzeQuality image has never been rebuilt with base: /apps/fuzequality/, and values-prod remains pinned at 6da67c73185a. Prod is half-migrated: #701 switched the route to /apps/fuzequality/*, but the image behind it is still built with base: '/', so its chunks resolve against the host shell's bundle. This unblocks the build.
