fix(vue-router): use Vue listener casing for external links

[Sheraff]

Note

This issue was not introduced by refactor-signals; the external-link path already bypassed Vue listener-name normalization before this branch. This PR fixes that pre-existing bug while targeting the branch under review.

Summary

• normalize Vue external link event props to emit DOM listener names like onMouseenter and onTouchstart
• accept both camelCase and Vue-style event prop variants so user hover and touch handlers still fire on external links
• add a regression test covering external Link hover and touch handlers

Testing

• CI=1 NX_DAEMON=false pnpm test:eslint
• CI=1 NX_DAEMON=false pnpm test:types
• CI=1 NX_DAEMON=false pnpm test:unit
