[PM-22241] Add DefaultUserCollectionName support to bulk organization user confirmation (#6153)

* Implement GetByOrganizationAsync method in PolicyRequirementQuery and add corresponding unit tests

* Refactor ConfirmOrganizationUserCommand for clarity and add bulk support

* Update ConfirmOrganizationUserCommandTests to use GetByOrganizationAsync for policy requirement queries

* Add DefaultUserCollectionName property to OrganizationUserBulkConfirmRequestModel with encryption attributes

* Update ConfirmUsersAsync method to include DefaultUserCollectionName parameter in OrganizationUsersController

* Add EnableOrganizationDataOwnershipPolicyAsync method to OrganizationTestHelpers

* Add integration tests for confirming organization users in OrganizationUserControllerTests

- Implemented Confirm_WithValidUser test to verify successful confirmation of a single user.
- Added BulkConfirm_WithValidUsers test to ensure multiple users can be confirmed successfully.

* Refactor organization user confirmation integration tests to also test when the organization data ownership policy is disabled

* Refactor ConfirmOrganizationUserCommand to consolidate confirmation side effects handling

- Replaced single and bulk confirmation side effect methods with a unified HandleConfirmationSideEffectsAsync method.
- Updated related logic to handle confirmed organization users more efficiently.
- Adjusted unit tests to reflect changes in the collection creation process for confirmed users.

* Refactor OrganizationUserControllerTests to simplify feature flag handling and consolidate test logic

- Removed redundant feature flag checks in Confirm and BulkConfirm tests.
- Updated tests to directly enable the Organization Data Ownership policy without conditional checks.
- Ensured verification of DefaultUserCollection for confirmed users remains intact.

* Refactor OrganizationUserControllerTests to enhance clarity and reduce redundancy

- Simplified user creation and confirmation logic in tests by introducing helper methods.
- Consolidated verification of confirmed users and their associated collections.
- Removed unnecessary comments and streamlined test flow for better readability.
