- Prior to this commit, the following error was encountered when applying the search filter within `/org_admin/templates`:
```
ActiveRecord::StatementInvalid - PG::AmbiguousColumn: ERROR: column reference "id" is ambiguous

^:

app/controllers/paginable/templates_controller.rb:25:in `index'
```
- Tracing the code reveals that the query encountering this error is `Template.includes(:org).latest_version.where(customization_of: nil).distinct.total_count`.
- Although `SELECT "templates.*"` is the default behaviour of the `.latest_version` scope, the ambiguity error is raised unless `.select('templates.*')` is added explicitly.
