improvement(storybook): bump Storybook from 10.3.5 to 10.4.6

[JeanMarcMilletScality]

What

Minor bump of Storybook within v10: 10.3.5 → 10.4.6.

Bumps the four lockstep packages:

• storybook
• @storybook/react-webpack5
• @storybook/addon-docs
• eslint-plugin-storybook

Why

Maintenance update that pulls in fixes directly relevant to core-ui's custom MDX docs:

• Primary/Controls blocks now render in custom MDX pages (10.4.3)
• Docs page no longer scroll-resets during HMR (10.4.3)
• Partial globals overrides in story/meta annotations (10.4.6)

No .storybook/ config changes required. The larger 10.4 features (git-based change detection, AI setup, TanStack React, the experimental RCM docgen analyzer) are not adopted here — the RCM docgen swap is worth a separate spike.

Verification

• npm install — clean, no peer/deprecation warnings
• npm run build-storybook — completed successfully, no errors (only the pre-existing webpack bundle-size advisory)
• All addon peer deps satisfied (@jbwatenbergscality/storybook-webmcp wants ^10.2.0; @chromatic-com/storybook supports through ^10.6)

Diff

Only package.json + package-lock.json.
