Title: [SENSOR] Build multi-location simulation

[ezehf2]

Update the sensor publisher scripts to simulate multiple rooms simultaneously rather than just one. Each sensor type should be able to run for room101, room102, and room103 at the same time, publishing to their respective topics as defined in config.json. Create a single launcher script called run_sensors.py in the sensors/ folder that starts all sensors for all rooms at once so the full simulation can be started with one command. Commit with message [SENSOR] Add multi-location simulation and reference this issue.
