Adds test_captured_pend_job_excluded_from_resinuse_until_run: drives a
job captured while still PEND through sched_account_jobs() and confirms
its resource-in-use contribution is zero; transitions the same job to
RUN and confirms sched_account_jobs() now includes its exact captured
allocation, with no second reconciliation call in between -- proving the
nonzero value comes from the earlier capture, not a fresh one.
Required promoting the file's sched_account_jobs() from a no-op stub to
a real reimplementation (verbatim body, matching the exact precedent
already established in test_sim_contention_parity.c and
test_sim_round_boundary_reconciliation.c) plus a resource.c white-box
include -- no production code touched.
