//! Number input widget with increment/decrement controls
//!
//! Provides a numeric input field with:
//! - Up/Down arrow key controls for increment/decrement
//! - Direct numeric entry
//! - Min/max value constraints
//! - Configurable step size and precision
//! - Optional prefix/suffix display (e.g., "$", "%")
