feat(scheduler-sim-live-allocation): make capacity checks core-safe (task 1.3)

Browse source 
Re-types sched_meet_host_selection(), sched_check_shared_satisfy()
(+its _ helper), sched_check_host_satisfy() (+its _ helper), and the
private unsatisfy_() helper they share, from xce_scheduler_t* to
xce_sched_core_t*, in resource.c.

Fixes every call site this forces (a C signature migration cannot
keep the build green otherwise): sched_try_alloc_on_host_() (2 sites,
already partially touched by task 1.2), host_iter.c's
sched_host_iter_next() (2 sites), and parjob_allocator.c/
seqjob_allocator.c's my_alloc() (1 site each) -- each fix is a minimal
&(sched->core) argument wrap, no algorithm change, preserving
host_iter/parjob/seqjob's own allocation algorithm exactly as-is.

Adds test_core_safe_allocation_chain_driver_parity, proving all three
functions produce identical grant/deny results whether given
normal-mode-shaped or simulation-mode-shaped core state.
