Struct TextDimensions 

pub struct TextDimensions { /* private fields */ }

TextDimensions - Centralizes ALL text layout and wrapping mathematical operations

Eliminates ad hoc text math like:

• width.saturating_sub(border_width)
• title_start_position = x1 + (width.saturating_sub(title_length)) / 2
• Text wrapping and line counting scattered throughout draw_utils.rs
• Character-aware truncation with ellipsis

Replaces scattered text layout logic from draw_utils.rs, components/text_content.rs
