Add ophyd_labels to device_info and summary

[cappel89]

cSAXS has a rather complex device 'EPS', which is about to be merged to csaxs_bec (https://gitea.psi.ch/bec/csaxs_bec/pulls/134). Here PVs indicating status values, temperatures, etc. are merged together. This information is currently spread across the various signals of the device, and encoded in either 'docs' or 'labels. To get a nice overview of the relevant information, I would like to extend the device serializer and summary method to also show _ophyd_labels passed as labels:set[str] to the ophyd components.

I was also considering adding the 'doc' field of sub-devices, but then dropped the idea again as this would require to unfold all nested sub-devices which could make the table printout rather confusing.

Pull request overview

Extends the device-info payload produced by the device server to include Ophyd component labels, and updates the client-side Device.summary() output to display those labels for a clearer overview of complex devices (e.g., aggregated status/temperature PVs).

Changes:

• Include _ophyd_labels_ in per-signal entries returned by get_device_info().
• Add a new “Labels” column to Device.summary() and populate it from serialized signal info.

Why sorted? And why BEC signal labels not sorted?

[cappel89]

Done, casted to sorted list of strings already in the device_serializer.
