Bug 32292: Add column descriptions to subscriptions table / complete items table

* Adds proper labels to the database columns for suggestions
* Adds missing item columns:
  * coded_location_qualifier
  * deleted_on
  * exclude_form_local_holds_priority
* Fixes spelling of item type, Uniform resource identifier

To test:
* Go to reports > Guided reports
* Select acquisition or another module using the items
* Make sure all entries for the tables items up with nice descriptions
* Changes to subscriptions: verify reading the patch, these don't seem to show
  up yet in guided reports.
