Definition links on propositions page should navigate to definitions page

Problem

On the /pages/propositions page, propositions display linked definitions in the metadata section under each proposition's title. The definitions appear as clickable links with format "Term (#N)" where N is the definition ID.

However, clicking these links does nothing - they use href="#" placeholder instead of actual navigation.

Expected Behavior

Clicking a definition link should navigate to the definitions page, ideally filtered to show the relevant term.

Current Location

The issue is in ratings-ui-demo/src/components/proposition-definition-horizontal-list.tsx line 25:

<Link href="#">
    {definition.term} (#{definition.definition_id})
</Link>

Proposed Fix

Change the link to navigate to the definitions page with a term filter:

<Link href={\}>
    {definition.term} (#{definition.definition_id})
</Link>

The definitions page already supports the term_contains filter parameter, which will show definitions matching the term.
