feat(api): accept several yards on each end of a route filter

Browse Source 
Bookings, contracts and train schedules all validated originYardId /
destinationYardId (originStationId / destinationStationId) as a single
@IsUUID and matched with `=`, so a list could be narrowed to exactly one
lane. The filter bar can now ask for several stations per end, and each
end independently, which needs the same on the server.

@IdListParam() is the shared transform: one id, a comma-separated list,
or a repeated query param, always landing as a string[]. It yields
undefined rather than [] when nothing usable is left — a repository that
branches on `?.length` can then never hand TypeORM an empty array, which
compiles to the syntax error IN (). It stays backwards compatible with
the single-value form, so existing deep links and saved views are
unaffected.

Matching moves to IN (:...ids) — for contracts inside the two existing
EXISTS subqueries, which keeps meaning "has a route from one of these
origins" AND "has a route to one of these destinations", not necessarily
the same route. All three statements were EXPLAIN-validated against
edr_dev.
