fix(lora): resolve network names that carry a dot in the filename

add_network keys available_networks by the basename with dots mangled to
underscores, and create_item looked the name up in that table using the
name as loaded, so any file with a dot in its stem missed and logged
"not registered". The tag pass then dropped the network's own tags and
used the filename instead. The lookup now falls back to the alias table,
which already carries the natural basename and the subfolder path.
