Journey: add regional-only filter and service notices

- connection_type setting (all/regional/long_distance) restricts EFA
  trip requests via inclMOT_N params, so ICE/IC/EC can be filtered out
  for commutes that only care about regional/local transit.
- Surface leg.infos[].infoLinks titles (real disruption/outage notices
  from EFA) on each journey row, marked with a red warning icon.
