[iOS] Fix gestures on iOS 26 (#3756)

## Description

Some changes in #3740 required follow up.

#### Tap

Turns out that we can leave `triggerAction` in `reset` (thank you apple
for transparent docs that clearly describe what changed between 18.5 and
26 ❤️).

It also seems that double `onFinalize` issue is fixed on 26.

#### Fling

Removing `[self triggerAction]` from `reset` broke things on old iOS.
Unfortunately now swiping in different direction does not result in
calling `onFinalize` - this should be handled by `triggerAction` in
`reset`, but now by default recognizers in `reset` have `Possible` state
(once again, thank you apple 😄). To fix that we will probably have to
rewrite fling to custom logic.

#### LongPress

`LongPress` was missing on `triggerAction` call that sends `fail`.

#### Pan 

In `Pan`, I've moved `triggerAction` calls from `touches*` methods to
`interactions*` methods.


## Test plan

<details>
<summary>Tested on basic-example and the following code:</summary>

```tsx
import { StyleSheet, View, Text } from 'react-native';

import {
  GestureHandlerRootView,
  Gesture,
  GestureDetector,
  GestureType,
} from 'react-native-gesture-handler';

function TestBox({
  gestureType,
  bgColor,
}: {
  gestureType: GestureType;
  bgColor: string;
}) {
  const handlerName = gestureType.handlerName;

  const gesture = gestureType
    .onBegin(() => {
      console.log(`[${handlerName}] onBegin`);
    })
    .onEnd(() => {
      console.log(`[${handlerName}] onEnd`);
    })
    .onFinalize(() => {
      console.log(`[${handlerName}] onFinalize`);
    })
    .runOnJS(true);

  return (
    <View style={styles.center}>
      <Text>{handlerName}</Text>
      <GestureDetector gesture={gesture}>
        <View style={[styles.box, { backgroundColor: bgColor }]} />
      </GestureDetector>
    </View>
  );
}

export default function App() {
  return (
    <GestureHandlerRootView style={[{ flex: 1, padding: 50 }, styles.center]}>
      <TestBox gestureType={Gesture.Pan()} bgColor="#b58df1" />
      <TestBox gestureType={Gesture.LongPress()} bgColor="#f1a85d" />
      <TestBox gestureType={Gesture.Fling()} bgColor="#5df1a8" />
      <TestBox gestureType={Gesture.Tap()} bgColor="#5d8ef1" />
    </GestureHandlerRootView>
  );
}

const styles = StyleSheet.create({
  center: {
    display: 'flex',
    justifyContent: 'space-around',
    alignItems: 'center',
  },
  box: {
    height: 100,
    width: 100,
    backgroundColor: '#b58df1',
    borderRadius: 20,
    marginBottom: 30,
  },
});
```
