NATS Registration Listener (fox100 + NetBox hostname/action_next lookup + timing + problem counter)
-----------------------------------------------------------------------------------------------
-------------------------------------------------------------------------------------------
- One device GET (status + tags + custom_fields.action_next), no duplicate fetch
- If fox100 and action_next present -> prepend 3x ASCII BEL to stdout line
- RabbitMQ publish logic is DISABLED for now:
* We still PREPARE the RabbitMQ message body
* We clearly log: "ok, here i will execute <content of rabbitmq message>"
* But we DO NOT actually POST it to RabbitMQ (publish call commented out)
- Keeps: nb_problems counter, timings, iface_id diagnostics, same formatting
- For fox100:
* If action_next is empty/absent -> print a simple stdout note and do nothing else
* If action_next is present -> PREPARE RabbitMQ /publish body and log:
"ok, here i will execute <body + decoded payload>"
(but DO NOT actually publish; publish call remains commented out)
* If action_next present -> prepend 3x ASCII BEL to stdout line (kept behavior)
