Enhancement - support Stomp WS message in the viewer

[SylvainNapoleon]

Hello

Stomp WS is used in spring application
https://spring.io/guides/gs/messaging-stomp-websocket

It would be nice to support Stomp message since it's a little bit different than a simple JSON message
for exemple :
a["MESSAGE\ndestination:/topic/taskExecution\ncontent-type:application/json\nsubscription:Task_Execution_Updates\nmessage-id:gqosafjq-27713\ncontent-length:265\n\n{\"subChannel\":\"TASK_LATE_OR_ALERT_COUNT\",\"messageFor\":null,\"deletedID\":null,\"taskList\":null,\"task\":null,\"taskListExecution\":null,\"taskExecution\":null,\"taskDueOverDTO\":{\"forDate\":\"2025-10-01\",\"atTime\":\"10:35:00\",\"due_size\":0,\"over_due_size\":0,\"due\":[],\"overDue\":[]}}\u0000"]

length:265 is almost the JSON size without '' 266

Message structure should be

a["MESSAGE
destination:<DESTIONATION>
content-type:application/json
subscription:<SUBSCRIPTION_NAME>
message-id:gqosafjq-27713
content-length:265
<JSON>
\u0000"]

Thanks

PR #34 will add a button to switch between raw data and the JSON View. We are using Stomp too.
@law-chain-hot I am using protobuf-controls as css class here maybe there is better way.
Havent tested it yet how it looks with Protobuff though.
But it works for the Stomp use case or with any use case where there is a valid JSON in the WS Message.
