refactor(frontier): remove AddOrganizationUsers RPC

[whoAbhishekSah]

Summary

• Removes the AddOrganizationUsers RPC, request message, and response message from FrontierService
• This RPC has been superseded by AddOrganizationMembers on AdminService, which supports explicit role assignment per member
• Server-side handler was already removed in refactor: centralize org member additions via membership package frontier#1548

Context

AddOrganizationUsers added members with a hardcoded viewer role and no way to specify the desired role. The replacement AddOrganizationMembers (on AdminService) accepts a role per member and is gated behind superadmin auth.

Test plan

• buf lint passes
• buf breaking passes (WIRE category allows RPC removal)

📝 Walkthrough

Walkthrough

This pull request removes the AddOrganizationUsers RPC endpoint from the FrontierService in the protobuf definition file. The removal includes the service method declaration and the associated AddOrganizationUsersRequest and AddOrganizationUsersResponse message types. This eliminates the defined API surface for this specific operation, reducing the available endpoints in the Frontier service API.
