RG-T125 Chatbot fix

PR Description: RG-T125 Chatbot fix

This pull request fixes an issue with the chatbot messaging functionality by addressing a protobuf serialization defect and adding fail-fast validation for queue message types.

Changes

1. Added missing [ProtoContract] attribute to ChatbotMessageQueueItem

   • The class was already decorated with [ProtoMember] attributes but was missing the required [ProtoContract] attribute at the class level. Without it, protobuf-net cannot properly serialize instances of this type, causing failures when chatbot messages are published to the RabbitMQ queue.

2. Extended the Protobuf serializer warmup to cover all queue payload types

   • SerializerHelper.WarmUpProtobufSerializer() now prepares serializers for every payload type published to RabbitMQ (e.g., CallQueueItem, MessageQueueItem, ShiftQueueItem, CqrsEvent, AuditEvent, etc.).
   • This builds the protobuf contracts at application startup, ensuring that any type missing the [ProtoContract] attribute fails immediately on boot rather than surfacing as a runtime error the first time a message of that type is enqueued.

Functional Impact

Chatbot messages will now serialize correctly for queue transport, and the application will detect missing protobuf contract attributes early during startup, preventing similar serialization failures across other message types.

📝 Walkthrough

Walkthrough

The protobuf warm-up routine now prepares multiple RabbitMQ queue and event payload serializers at startup. ChatbotMessageQueueItem is marked with ProtoContract so it can participate in protobuf serialization.

Changes

Protobuf serializer warm-up

Layer / File(s)	Summary
Contract and startup registration Core/Resgrid.Model/Queue/ChatbotMessageQueueItem.cs, Core/Resgrid.Model/Helpers/SerializerHelper.cs	ChatbotMessageQueueItem gains the ProtoContract attribute, and WarmUpProtobufSerializer() prepares additional queue and event payload serializers during startup.
