pmrmodel: db access for remaining exposure types

- Just the core implementation for the existing methods.
- Change the exposure schema to reference the view instead of just
  setting a potentially dangling text reference.
- Also updated the foreign key definitions for the exposure for the
  default reference, along with a rename of the field to make it
  consistent.
