Function render_kv_table 

pub fn render_kv_table(
    f: &mut Frame<'_>,
    area: Rect,
    title: &str,
    shortcut: Option<u8>,
    rows: &[KvRow],
    scroll: u16,
    focused: bool,
    theme: &Theme,
)

Render a scrollable key-value table inside area.

• Section KvRow::Headers are rendered full-width in Theme::section_header.
• KvRow::Field rows split the inner width: key column (right-aligned, Theme::hint) and value column (left-aligned, Theme::body). The key column width is the minimum of the longest key in rows and 30% of the inner width.
• KvRow::Separator renders a blank line.
• scroll skips the first N logical rows before rendering.
