Each queued action now resolves to its move's cutscene
(cutscenes/battle/moves/<name>.jsonc), spliced into the executing state
with a BATTLE_POST_MOVE checkpoint after each one. Fighter turn order is
tracked via fighterOrder/fighterOrderCount, and resolved actions/pending
counts are cleared so fighters aren't skipped in later rounds. Also fixes
a BATTLE_WAIT_SELECTION deadlock and adds an optional "blocking" flag to
MODAL cutscene items.
