Maurice 3c87d37cd9 feat(planner): make transit journeys first-class entries (#1065)
A saved transit route is now its own reservation type instead of piggybacking
on train/bus: it gets a tram icon and its own color everywhere, and the day
timeline renders the itinerary inline — line badges in their official colors
with walk segments, plus the transfer count and walking time — instead of a
generic transport row.

Clicking the row opens the itinerary view (journey summary, stop-by-stop legs
with times, platforms, headsigns and operators) rather than the edit form;
editing stays reachable from an Edit action inside that view. The transit
type is registered across the timeline merge, transport modal, reservations
panel, file manager, map overlays and detail panels, with a translated type
label in every locale.
