…einforcing robustness.

Simplified and centralized the testing of diversified name cases and edge-cases for 'NameFixTest.php' in the 'testNameFix' function by using arrays, leading to increased readability, improved coverage and enhanced robustness of the tests. This was supplemented with the addition of a new '!@#$%' test case in the 'negativeTests' array, while keeping the 'testNameFixWithNumericInput' function unchanged. Additionally, the NameFixTest class documentation and comments were improved to provide a clearer understanding of the class's purpose and its methods, particularly the testNameFixFunction and testNameFixWithNumericInput methods. By consolidating individual test methods into a more manageable and efficient loop and array structure, this commit extensively optimizes the NameFixTest. This restructured test now comprehensively covers a wider spectrum of conditions, including simple names, names with accents, and special characters.
