refactor: standardize Input component prop naming

Replaces `className` prop with `extraClassName` across Input and PasswordInput components for consistency.

Updates PasswordInput to use numeric `topOffset` instead of string `topPosition` for better type safety and clearer intent.

Adds uncontrolled mode support to PasswordInput with internal state management and optional `defaultShowPassword` prop.

Removes unnecessary margin classes from various View components to clean up spacing.
