PM-6059 - allow copilot search in talent search

[vas3a]

This pull request adds support for filtering and displaying members with the "Copilot" platform role in the member search API. It introduces a new copilot filter to the search request, updates the SQL query to join and filter on copilot role assignments, and ensures that the isCopilot property is always included in the member search results. The changes are covered by new and updated tests.

Copilot Role Support in Member Search

• API and DTO Changes:

  • Added an optional copilot boolean filter to MemberSearchBodyDto to allow searching for members with the Copilot role.
  • Added an isCopilot boolean property to MemberResultDto to indicate Copilot role status in results.

• Service and Query Updates:

  • Updated the SQL query in member-search.service.ts to include a new copilot_members CTE, filter by Copilot role when requested, and always select the Copilot indicator for each member. [1] [2] [3] [4] [5]
  • Extended the RawMemberRow type and related service logic to handle the new isCopilot field. [1] [2]

• Test Coverage:

  • Updated and added tests in member-search.service.spec.ts to verify Copilot filtering, result mapping, and SQL generation. [1] [2] [3] [4]
  • Updated controller tests to include the isCopilot field in expected results.
