feat(scheduler-sim-decision-parity): relocate resource accounting to core-level (task 1.1)

Browse source 
Relocates sched_account_jobs()/sched_charge_account()/sched_uncharge_account()/
sched_update_account()/sched_update_res_accounts()/sched_commit_job_alloc()
from xce_scheduler_t* to xce_sched_core_t*, mirroring the sched_resolve_job_picker()
precedent, so the simulation driver can call the same accounting service the
normal-mode driver already uses. Pure signature relocation -- every body
reference was already sched->core.*, no logic change. Updates the 3 real call
sites (driver.c's normal-mode round, scheduler.c's sched_begin_session and
sched_commit_decision) and 7 existing tests' link-satisfying stub signatures.

Adds test_resource_accounting.c proving Requirement 1.4: the relocated
accounting produces identical resInUse/sharedInUse output whether called
against a core embedded in xce_scheduler_t or xce_sched_sim_driver_t.

43/44 scheduler tests pass; the 1 failure is pre-existing bug-1560
(unrelated recording.c sandbox-permission ordering issue).

* sched_account_jobs/sched_charge_account/sched_uncharge_account/
* sched_commit_job_alloc - resource-in-use accounting (scheduler-sim-
* decision-parity spec, task 1.1). Relocated from scheduler.c/resource.c's
* xce_scheduler_t* signature to this xce_sched_core_t* signature, following
* the exact same precedent sched_resolve_job_picker established above (task
* 4.3): pure signature relocation, body unchanged -- every reference in
* these functions' bodies already only touched sched->core.* before this
* move. Moved so the simulation driver (which has no xce_scheduler_t* of
* its own, only xce_sched_core_t) can call the same accounting service the
* normal-mode driver already uses, restoring the resource-in-use accounting
* parity `.kiro/steering/scheduler-driver-equivalence.md` documents.
*
* sched_account_jobs() - re-derives resInUse/sharedInUse from every
* currently-running job's known resource allocation (job->accounts != NULL)
* by re-charging each one via sched_charge_account(). Skips a RUN-state job
* whose allocation is not yet known -- not an error; see
* scheduler-sim-decision-parity design.md's Recorded-Decision Reconciliation
* component for why that is the expected state before this call runs.
* Callers (both drivers) must call this strictly after the session's resval
* reset and strictly before the picker/allocator are unblocked -- see
* xce_core_begin_session()/xce_core_signal_go()'s own doc comment below for
* the full ordering contract this depends on. Was exported (no longer
* `static`) as of scheduler-core spec task 5.2 for the identical reason;
* still defined in scheduler.c, only its declaration/signature move here.
*
* sched_charge_account()/sched_uncharge_account() - add/remove one job's
* xce_job_account_t (shared + per-host resource usage) to/from
* core->sharedInUse and each worker's resInUse.
*
* sched_commit_job_alloc() - charges a job's already-resolved allocation
* (job->accounts) via sched_charge_account(); a no-op (returns 0) if the
* job's allocation is not yet known. Called by sched_commit_decision()
* (scheduler.c) immediately after a fresh DISPATCH decision populates
* job->allocs/job->accounts.
