Set default `synapsectl logs` to something that doesn't return an error

[kalashb]

Right now, synapsectl --uri {device_name} logs command straight up throws an error - at least in the contexts I've used it so far

>>> synapsectl --uri {device_name} logs                 
( ●    ) Getting logs...[07/17/25 10:58:03] ERROR    ERROR:synapse.client.device:Error:               device.py:164
No logs found for the specified criteria

This works: synapsectl --uri wapiti-of-splendid-certainty logs --log-level DEBUG --follow

But in my opinion it isn't clear from the help message what it does. Also maybe it shouldn't return ERROR on the default logs comment.

>>> synapsectl --uri wapiti-of-splendid-certainty logs --help
