Add station listing and cargo queries to admin client
Extends the AdminBridge GameScript JSON channel (the same relay used by
list_vehicles/get_timetable) with station support:

- list_stations(): enumerate stations, fire-and-forget like list_vehicles().
- get_station(): authoritative per-cargo snapshot of a station's live state,
  with both the real-time waiting amount (GSStation.GetCargoWaiting) and the
  planned cargodist link-graph flow (GetCargoPlanned), plus rating.
- get_station_cargo(): break one cargo type down by source station and by
  next hop (the cargodist routing destination) for both waiting and planned
  amounts, with optional from_station/via_station filters.

All three use stock GameScript API (no server patch, unlike timetables).
Refactors the shared GS request/reply correlation out of get_timetable and
get_station into a _gs_query() helper. Companion handlers must be added to
the server-side AdminBridge GameScript (not tracked in this repo).

Includes unit + e2e tests, a worked demo in main_admin.py, and protocol docs.

the next hop ("via").

Optional filters narrow the query:

- via_station: only cargo whose next hop is this station.
Passing from_station restricts the by_via breakdown to that source (and the totals to it);
