fix(scheduler): wire mem reservation reconciliation into live rusage event path

Browse source 
sched_reconcile_job_resource_usage() was only reachable from
sched_apply_job_rusage() (scheduler.c's sched_update(), which has no live
caller), so real-usage reconciliation never actually ran outside tests.
Wire it into core_events.c's XCE_CORE_EVENT_JOB_RUSAGE handler instead,
the actual live path shared by both normal-mode (driver.c) and sim/replay
mode (sim_loop.c). Adds link-satisfying stubs to the testsuite files that
#include core_events.c directly.
