Extract the pre-casualty defender report block into a new private method
collectReinforcementReport(): reset and rebuild the reinforcement unit totals
($DefenderEnf) and per-tribe hero totals from a fresh re-select, fold
reinforcement heroes into the defender's hero count, build the "units sent"
report rows (own troops + reinforcements and their masked variants), and
(re)initialise the per-tribe dead-hero accumulator. The bundle is returned to
the caller and the defender's folded hero count is reassigned at the call site.
Pure behaviour-preserving extraction. Method name matches the maintainer's
roadmap for #155.
