fix(scheduler): record events before the core applies them (bug-1852)
The recorder encoded each controller event batch after
xce_core_push_events() had applied it, and applying moves payload fields
out of the events: a WORKERS_PUSH's resvals (core_apply_worker_resvals
MOVE_PTR), a JOBS_PUSH's allocs, a JOB_RUSAGE's rusages, and a
CONFIG_PUSH's shared resvals (sched_apply_pending_config recorded after
sched_init_config). Recordings silently lost exactly those fields -- a
worker's resval names were written with NULL values, so --sim-verify
replayed "no slots" and turned 3 live DISPATCHes into PENDs.

driver.c now records the batch before the push; the periodic in-stream
SnapshotEntry moves out of sched_record_write_events() into new
sched_record_checkpoint_after_apply(), called after the push so a
checkpoint still reflects the events written ahead of it. The config
push is likewise recorded before sched_init_config().

Regression test: test_recorded_workers_push_keeps_resval_values (RED:
recorded value NULL; GREEN after). Periodic-checkpoint tests updated to
the write-then-checkpoint contract. meson test 109/109; 25 live soak
recordings replay with 0 mismatches.
