Strategist Role should be able to run queries (and see totals)

**Is your feature request related to a problem? Please describe.**
As a User with a Strategist Role, I would like to run queries AND only receive `total` counts (without any contact PII/info)

**Describe the solution you'd like**
On a List Query, instead of returning counts AND post/record details:

```
{
"posts": [
...redacted record info
],
"total": 2
}
```

Only return the aggregate counts/total:

```
{
"total": 2
}
```

**Describe alternatives you've considered**
I attempted creating a Custom Role, but the options are not granular enough. Current approach is to use at least Dispatcher Role, but some partners have questioned why this level of access is required for reporting metrics.

**Additional context**
Current response with Strategist Role to the following query:

```
{{url}}/wp-json/dt-posts/v2/contacts?quick_button_meeting_complete[operator]=>&quick_button_meeting_complete[number]=5
```

```
{
"code": "search_viewable_post",
"message": "You do not have access to these",
"data": {
"status": 403
}
}
```
