minor fix to regression of post seeds after introducing rubocop

Fix minor regression to post seeds, introduced in #432

I broke generating enhanced post content seeds when I shortened the method and messed with the implicit return, so we ended up with a '3' instead of a bunch of html content

PR also includes a single character white space fix to satisfy herb, probably I failed to push that fix when raising this earlier PR

Pull request overview

This PR fixes a regression in post seed data generation that was introduced when refactoring code for Rubocop compliance. The post_content_enhanced method was not explicitly returning the generated HTML content, causing posts to display "3" (the return value of 3.times) instead of the full content.

Changes:

• Added explicit content return statement to post_content_enhanced method
• Consolidated string concatenations on lines 41 and 45 for improved readability
• Added blank line before return statement for code style consistency

I'm surprised Herb didn't complain about <br /> as the W3C validator now prompts warnings against the use of self closing brackets.
