Two test callsites in AdminControllerTests still constructed ImportMissionMeta
with the pre-fix types (bool HasReceivedPickTwoMission, long MissionChangeTime),
which compiled locally against the stale test binaries under --no-build but
tripped CS0029 in CI on a clean build. Switch to wire-shape values (int 1,
"yyyy-MM-dd HH:mm:ss" string) and adjust the round-trip assertion to compare
against the parsed-UTC DateTime rather than the Unix conversion.
