[BUG] The related methods of Inspector basically lack the transmission of ctx about asynq

I think asynq inspector don't need context in function. inspector is only called by asynqmon in order to inspect asynq now. why do you need ctx ?

2. Add ctx for request timeout control, opentelemetry tracing and other functions have been expanded
