Pull Request Overview

This PR implements an obscure input component for password entry by introducing an “obscure” flag that toggles between showing the real value and an obscured version. Key changes include updating rendering logic in the Input widget, modifying the data models (InputSnap, InputSnaps, Input) and their constructors to support the new flag, and propagating the flag through configuration and adapter layers.
