[PM-39976] Scaffold PAM lease endpoints

[Hinton]

🎟️ Tracking

https://bitwarden.atlassian.net/browse/PM-39976

📔 Objective

Adds the /leases Minimal API group (active, history, mine, revoke, extend) with an intentionally unimplemented handler, following the access-rule and access-request scaffolds.

The response models are already on main; the two new request DTOs (revoke, extension) carry the remaining wire contract. Contract tests lock the routes, names, methods, and return types the generated spec is built from.

🤖 Bitwarden Claude Code Review

Overall Assessment: APPROVE

Reviewed the PAM /leases scaffold: the Minimal API group (active, history, mine, revoke, extend), its intentionally-unimplemented handler, two new request DTOs, DI registration, and the contract tests. The endpoints, handler stubs, DI wiring, and tests faithfully mirror the established access-request and access-rule scaffolds. The Extend handler returning AccessRequestDetailsResponseModel is consistent with the domain model (extensions produce an auto-approved access request, per ExtensionOfLeaseId).

Code Review Details

• 🎨 : Documented constraints on the extension DTO aren't expressed as DataAnnotations, so they won't be enforced by PamValidationEndpointFilter or appear in the generated OpenAPI schema
  • bitwarden_license/src/Services/Pam/Api/Models/Request/AccessLeaseExtensionRequestModel.cs:12
