/**
 * LEDMatrix Schedule Picker Widget
 *
 * Composite widget combining enable toggle, mode switch (global/per-day),
 * and time range configurations. Composes day-selector and time-range widgets.
 *
 * Can be used standalone in schedule.html or by plugins via x-widget: "schedule-picker".
 *
 * Schema example:
 * {
 *   "schedule": {
 *     "type": "object",
 *     "x-widget": "schedule-picker",
 *     "x-options": {
 *       "showModeToggle": true,     // Allow switching global/per-day
 *       "showEnableToggle": true,   // Show enabled checkbox
 *       "compactMode": false,       // Compact layout for embedded use
 *       "defaultMode": "global"     // Default mode: "global" or "per_day"
 *     }
 *   }
 * }
 *
 * API-compatible output format:
 * {
 *   enabled: boolean,
 *   mode: "global" | "per_day",
 *   start_time: "HH:MM",           // if global mode
 *   end_time: "HH:MM",             // if global mode
 *   days: {                        // if per_day mode
 *     monday: { enabled: boolean, start_time: "HH:MM", end_time: "HH:MM" },
 *     ...
 *   }
 * }
