 * Calculates the width needed for an action column based on button content.

 * When `featuredActions` is provided, the calculation accounts for the
 * featured/overflow split pattern (inline buttons + dropdown trigger):
 * - featuredActions = 0: auto-CRUD mode — CRUD buttons shown inline, rest in dropdown.
 *   Width accounts for all CRUD buttons (worst-case, including delete).
 * - featuredActions > 0: featured button widths + dropdown trigger (if overflow)
 * - featuredActions >= total: all buttons inline, no dropdown (same as legacy)
 *
 * When `featuredActions` is not provided, all buttons are treated as inline
 * (backward compatible with legacy behavior).
 *
 * Calculation uses actual MUI small outlined Button metrics:
 * - Text width: ~6.5px per character (13px font-size, proportional sans-serif)
 * - Icon width: 24px (18px icon + 8px margin - 2px offset)
 * - Button padding: 18px (9px left + 9px right for small outlined)
 * - Dropdown trigger: 36px (18px padding + 18px icon)
 * - Spacing: 0px (ButtonGroup collapses borders)
 * - Column padding: 20px (DataGrid cell padding ~10px per side)
 *
 * @param buttons Array of buttons to display in the action column
 * @param featuredActions Number of featured actions to show inline (from ButtonGroup model)
 * @returns Calculated width in pixels
