Add boolean field conversion

[krangadurai]

Description

Purpose: This commit integrates the conversion of specific fields to boolean values in the find method to ensure consistent data representation when returning API data.

MySQL Boolean Representation: In MySQL, boolean fields are typically stored as integers, with 1 representing true and 0 representing false. However, for many API responses, it is preferable to return these fields as actual boolean values (true/false).

Automatic Conversion: The convertBooleanFields method is called after data retrieval and the afterFind event, ensuring that any specified fields are converted from 1/0 to true/false before the data is returned.

API Consistency: This conversion helps maintain consistency in API responses, aligning the data format with common expectations for boolean values in JSON and other data formats, where true and false are native boolean types.

Why don't you use Model Field Casting int-bool ?
Is it something wrong?
