docs(style): address PR review feedback

- Add `"type": "dark"` to ev-dark.json theme manifest
- Raise punctuation token contrast from #505050 to #767676 (WCAG AA)
- Align --vp-code-block-color CSS var with ev-dark default text (#dbd7ca)
- Use ThemeRegistration type instead of `as any` in config.ts
