Render basic markdown in content titles

Summary

Content titles do not render basic markdown. The reporter requests that basic markdown (e.g., bold, italic, inline code) be rendered in titles, but only a safe subset should be allowed.

Steps to Reproduce

1. Navigate to a profile page (e.g., https://devplace.net/profile/retoor).
2. Observe the content title displayed on the page.
3. Note that any basic markdown syntax in the title is not rendered.

Expected Behaviour

Basic markdown (e.g., bold, italic, inline code) should be rendered in content titles, using a safe subset of markdown.

Actual Behaviour

Content titles display raw markdown syntax without rendering.
