feat(auto-form): add new fields and form files to AutoForm component

Added several files to the AutoForm component for better form functionality including a file for each type of input field (checkbox, date, enum, file, number, radio-group, switch, etc). Managed the configurations in a separate file and handled dependencies to control form behaviours. This commit enhances form handling capabilities and simplifies the process for creating versatile forms.
