fix(flomni): unpack sample owner on the status webpage

FlomniWebpageGenerator._collect_setup_data() read the raw
flomni_samples.sample_names.sample0 DESC signal directly, so once
7e8e807 started packing "name | owner" into that same field (there's
no separate PV for owner), the status page showed the raw
delimiter-joined string as the sample name instead of unpacking it --
same gap FlomniSampleStorage.get_sample_name_and_owner()/show_all()
already handle correctly. Now unpacks via sample_desc_codec.unpack_desc()
and appends "(owner: ...)" when set, mirroring show_all()'s own format.

Lamni has no equivalent gap: it has no automatic sample changer or
storage, so its sample_name global var was never given an owner field.
