[DEV-3702] Enhance validation and error handling in SignUpForm and ProfileDataCard

[Sebastiano-Bertolin]

This pull request introduces improved validation and error handling for profile and sign-up forms, focusing on name fields and maximum character limits. The main changes include new validation logic, error messaging, and UI updates to display validation errors to users.

List of Changes

Validation and error handling improvements:

• Added a new validateName function to enforce stricter rules for name fields, including allowed characters and a maximum length of 50 characters. Also updated validateField to check for empty values and a maximum length of 100 characters.
• Updated the sign-up form and profile data card to use the new validation functions, ensuring that errors are displayed with specific messages for invalid names and overlong values.
• Introduced an error prop to ProfileDataCardItem and RequiredTextField components, allowing error messages to be shown directly under the relevant input fields.
• Updated UI logic in profile editing to clear errors when fields are corrected and reset errors when cancelling edits.
• Added new localised error messages for maximum length and name validation in both English and Italian message files.

UI and code quality updates:

• Fixed typo in input prop from maxlength to maxLength for consistency with React standards.
• Improved error display logic in RequiredTextField to show helper text and error state only when appropriate.
• Added debug logging for error values in form components to aid development.
