Block reports fixes (#1929)

**Story card:** [ch2175](https://app.clubhouse.io/simpledotorg/story/2175/block-reports-user-wise-data-missing)

User-wise data tables in the Details section of facility reports were missing.

The underlying cause is: The Details section wasn't handling the distinction between facilities and non-facility regions correctly. Comments are inline for reviewers.

**Recommend reviewing with whitespace ignored**
