Touch events blocked after dismissModal on iOS + dismissModal animation options not respected #8279

Summary

Fixes #8279 — touch events blocked after dismissModal on iOS and dismissModal animation options not respected.

Root cause

Animation options like animations.dismissModal.enabled = false were being silently overridden by an unrelated mergeOptions: path. The culprit was the waitForRender parser in TransitionOptions.mm, RNNScreenTransition.mm, and RNNComponentOptions.mm:

self.waitForRender = [Bool withValue:[[BoolParser parse:dict key:@"waitForRender"]
                                       withDefault:[RNNUtils getDefaultWaitForRender]]];
