feat(data): add seven Brazilian Bike Itaú cities to the GBFS registry

São Paulo, Rio de Janeiro, Salvador, Recife, Porto Alegre, Brasília and
Curitiba run on the same PBSC platform as the existing Austin, Honolulu
and Chattanooga entries, so they need no new feed handling and no proxy
allowlist change — isAllowedGbfsHost already accepts *.publicbikesystem.net.

These are the layer's first stations outside the United States: 1,017
stations across the seven systems.
