Move set_on_changed registrations from on_process() to __init__()

Callbacks were registered inside the async on_process() coroutine,
meaning they weren't active until the event loop started ticking.
Moving them to __init__ ensures they're wired up at construction time.
Also removes remaining debug prints from the affected task files.
