Report Grid: replace entity_field_reference column with the qualifier columns

[davidwatkins73]

Description

On the report_grid_column_definition table the existing entity_field_reference_id and the new qualifier columns (column_qualifier_kind and column_qualifier_id) can be consolidated.

The entity_field_reference_ids can be expressed as qualifier columns (with a kind of ENTITY_FIELD_REFERENCE).

Steps:

• [ ] update col def table to copy the field ref id value into the qualifier (and add the kind)
• [ ] Update the DAO code to retrieve cell data from their
• [ ] Rework the col editor to understand the new representation of extension fields
• [ ] Drop the column

Resourcing

We intend to implement this task

This should only be attempted after #6188 has been merged

Not 100% sure we should do this. Thinking of the scenario where we want to do something like:

• Show grid cols for measurable category attestations.
  • One col is the time it was attested,
  • the other column would be who attested it.
• We would need the field_ref to give that extra level of detail.
