Search result titles skip a heading level (h1 to h3)

Problem/Motivation

On the search results page the page title is an h1 and every result card title is an h3, so the heading outline skips the h2 level. Editoria11y reports it as "headingLevelSkipped" for an editor browsing the page, and screen reader users who navigate by heading level meet a jump from level 1 to level 3. The filter headings further down the page (Category, Content Type, Date Published) are h2.

Steps to reproduce

1. Log in as a user who can see Editoria11y and open /search?keywords=design.
2. The checker panel flags the first result heading; the outline reads h1, h3, h3, ... then h2.

Proposed resolution

Set the heading level to 2 in the news and podcast episode search_result content templates (canvas.content_template.node.news.search_result and canvas.content_template.node.podcast_episode.search_result). The visual size does not change because the heading component sets its own text size.
