Add prettier sort import plugin

[DecampsRenan]

We want imports to be sorted like they are in start-ui-web; cf. prettier config: https://github.com/BearStudio/start-ui-web/blob/v2-going-full-stack/.prettierrc.js

Currently they are like this:

import { Formiz, useForm } from '@formiz/core';
import { FieldInput } from '@/components/FieldInput';
import { TextInput } from 'react-native';
import { useRouter } from 'expo-router';
import { useRef } from 'react';
import { Button, Stack } from 'react-native-ficus-ui';
import { focus } from '@/utils/formUtils';
import { isEmail } from '@formiz/validations';
import { useLogin } from '@/modules/auth/auth.service';

We want them something like this:

import { useRef } from 'react';
import { TextInput } from 'react-native';
import { Button, Stack } from 'react-native-ficus-ui';

import { useRouter } from 'expo-router';
import { isEmail } from '@formiz/validations';
import { Formiz, useForm } from '@formiz/core';

import { focus } from '@/utils/formUtils';
import { useLogin } from '@/modules/auth/auth.service';
import { FieldInput } from '@/components/FieldInput';
