fix(gbfs): read underscores in station names as word breaks

JCDecaux's Spanish contracts prefix every station name with "_", and
Valenbisi joins its words with it ("_PLAZA_MUSICO_LOPEZ_CHAVARRI"), so
the card and HUD would show the raw identifier. The shared parser now
reads a run of underscores, with the spaces around it, as one word break
and trims the ends. It applies to `name`, the `short_name` fallback and
GBFS v3 localized names, so the layer and get_bike_share both read it.

No registered system changes: run over all 52 live station_information
feeds on 2026-10-17, the old and new parsers give identical names for
all 13,397 stations. Other spacing stays as the operator published it.
