[PM-23134] Update PolicyDetails sprocs for performance (#6421)

* Add integration tests for GetByUserIdWithPolicyDetailsAsync in OrganizationUserRepository

- Implemented multiple test cases to verify the behavior of GetByUserIdWithPolicyDetailsAsync for different user statuses (Confirmed, Accepted, Invited, Revoked).
- Ensured that the method returns correct policy details based on user status and organization.
- Added tests for scenarios with multiple organizations and non-existing policy types.
- Included checks for provider users and custom user permissions.

These tests enhance coverage and ensure the correctness of policy retrieval logic.

* Add UserProviderAccessView to identify which organizations a user can access as a provider

* Refactor PolicyDetails_ReadByUserId stored procedure to improve user access logic

- Introduced a Common Table Expression (CTE) for organization users to streamline the selection process based on user status and email.
- Added a CTE for providers to enhance clarity and maintainability.
- Updated the main query to utilize the new CTEs, improving readability and performance.
- Ensured that the procedure correctly identifies provider access based on user permissions.

* Refactor OrganizationUser_ReadByUserIdWithPolicyDetails stored procedure to enhance user access logic

- Introduced a Common Table Expression (CTE) for organization users to improve selection based on user status and email.
- Updated the main query to utilize the new CTEs, enhancing readability and performance.
- Adjusted the logic for identifying provider access to ensure accurate policy retrieval based on user permissions.

* Add new SQL migration script to refactor policy details queries

- Created a new view, UserProviderAccessView, to streamline user access to provider organizations.
- Introduced two stored procedures: PolicyDetails_ReadByUserId and OrganizationUser_ReadByUserIdWithPolicyDetails, enhancing the logic for retrieving policy details based on user ID and policy type.
- Utilized Common Table Expressions (CTEs) to improve query readability and performance, ensuring accurate policy retrieval based on user permissions and organization status.

* Remove GetPolicyDetailsByUserIdTests

* Refactor PolicyRequirementQuery to use GetPolicyDetailsByUserIdsAndPolicyType and update unit tests

* Remove GetPolicyDetailsByUserId method from IPolicyRepository and its implementations in PolicyRepository classes

* Revert changes to PolicyDetails_ReadByUserId stored procedure

* Refactor OrganizationUser_ReadByUserIdWithPolicyDetails stored procedure to use UNION instead of OR

* Reduce UserEmail variable size from NVARCHAR(320) to NVARCHAR(256) for consistency in stored procedures

* Bump date on migration script
