fix(undo-redo): use consistent target state for toggle redo

The redo logic for BATCH_TOGGLE_ENABLED and BATCH_TOGGLE_LOCKED was
incorrectly computing each block's new state as !previousStates[blockId].
However, the store's batchToggleEnabled/batchToggleLocked set ALL blocks
to the SAME target state based on the first block's previous state.

Now redo computes targetState = !previousStates[firstBlockId] and applies
it to all blocks, matching the store's behavior.
