🤖 Bitwarden Claude Code Review

Overall Assessment: APPROVE

This PR moves OrganizationCollectionManagementUpdateRequestModel from Bit.Api.Models.Request.Organizations to Bit.Api.AdminConsole.Models.Request.Organizations so the file is covered by the Admin Console team's CODEOWNERS rule (**/AdminConsole @bitwarden/team-admin-console-dev). The class body is unchanged; only the namespace and file path are updated. The three call sites (OrganizationsController.cs, OrganizationsControllerTests.cs, OrganizationAbilityCacheTests.cs) have their using directives updated accordingly, and no behavior is affected.

Code Review Details

No findings. Verified:

• The new namespace matches the 15 existing sibling files in src/Api/AdminConsole/Models/Request/Organizations/.
• No remaining references to the old namespace for this specific class.
• Removing using Bit.Api.Models.Request.Organizations; in OrganizationsControllerTests.cs is safe — the file already had using Bit.Api.AdminConsole.Models.Request.Organizations; and no other type from the old namespace is used.
• The move aligns with the stated CODEOWNERS cleanup objective (PM-13328).
