feat(transit): name Rio routes from SMTR's published GTFS

SMTR's realtime feeds carry internal route keys, so a Rio card read
"Route O0731AAN0A" where riders know line SN731. Join both feeds to the
route_short_name in SMTR's static GTFS routes.txt (CC BY 4.0, same
publisher and terms). The keys cannot be parsed: O0014AAA0A is LECD135.
A 2026-11-04 snapshot found all 282 bus and 21 BRT routes in service in
the table; an unknown key still falls through raw.
