fix meta code

[arhimede]

1. do not trim anything in meta description. Keep it at 160 characters as is provided.

2. og:site_name is Dotkernel Light — the skeleton's name, left over from the template.
   use the $app->'meta' ->'title' for consistency

3. og:url is https://www.dotkernel.com but is https://new.dotkernel.com/. They disagree, and the canonical points at the temporary domain rather than the final one.

• <title> has a trailing space before </title>.

Use $baseUrl
