Adding Test Suite for the Input Component

[mrsants]

We need to introduce a test suite to ensure stability and predictable behavior for the Input component. The name, disabled, and other core props were recently expanded, and tests will help prevent regressions and support safer future contributions to the library.

Example of required/essential Input props:

• name: field identifier for forms
• value: controlled input value
• onChangeText: updates state on text change
• placeholder: helper text
• keyboardType: keyboard type (email, numeric, etc.)
• disabled: disables the field when needed
