fix(transit): read Rouen and Le Havre from the operators' own feeds

Rouen now reads Métropole Rouen Normandie's TCAR vehicle feed
(api.mrn.cityway.fr) and Le Havre LiA's own GTFS-RT
(opendata.transports-lia.fr), both listed in their transport.data.gouv.fr
records, instead of the unofficial bus-tracker.fr relay. LiA ids carry an
8- prefix, so a new liaRouteLabel strips it and liaRouteMode reads the line.

Keyless official gateway; no licence found. Same basis as Metro Transit and OVapi. Carries neither bearing nor speed, and vehicle reports run about a minute old. Route ids append a variant. | Carris |
 | **BAS.MY Johor Bahru** (api.data.gov.my) | Transit layer live vehicles, Johor Bahru, Malaysia | CC BY 4.0 (https://developer.data.gov.my/realtime-api/gtfs-realtime). Stated: “All GTFS Realtime feeds are licensed under CC BY 4.0.” Served keyless by Malaysia’s national open-data API, which caps GTFS Realtime at 4 requests a minute and refreshes positions every 30 seconds, so the proxy caches this feed for 30 seconds. Without the trailing slash the API redirects. Route ids append an operator code. | BAS.MY / data.gov.my |

The metropolis publishes its realtime data under the Licence Ouverte (dataset record quoted); this registry reads it through bus-tracker.fr, an unofficial relay that merges the city’s networks into one GTFS-RT file.
