Improve individual page screen

[dvidsilva]

In pages like /about /newsletter /events it displays some default information, or it displays data from the API if available

We can change the screen to loook more like this template

The content is stored as Strapi content blocks, there's some limitations on the kind of content and how it stores it, but we should try and work around this to make it nicer, trying to alternate some headers or images so the pages don't beecome boring

Some pages have other pages and items nested, like /events, they can use the new reusable components for design consistency

Expected

Big image takes a larger percentage of the screen

Title looks better

Paragraphs look better

Image links in the content are turned into images that are displayed in block or inline

Propose any valid changes to improve the look

It works well in mobile and wide screens

Users can read comfortably
