Admin can see a daily report on the site

[php-coder]

In order to simplify testing we can add another view for a daily report -- as a simple page with text (not HTML) that admin can open at any time.

Source code that could be helpful:

• a mail template
• service that prepares a report
• report DTO

Additional details:

• localization is not required
• page should be available only to a users with a specific authority. We should create such authority and grant it to admin
• let's create ReportController and map this page to /report/daily URL
