/**
* Pre-search filter drawer. Renders the product-name field, then walks
* `TableColumns()` in column-config order and emits one accordion section
* per column with a `meta.drawer` payload (via `ColumnDrawerSection`). The
* non-column "Results Limit" section is injected just before the `price`
* entry to preserve its historical position.
*
* Adding, removing, or reordering a drawer-backed column in TableColumns.tsx
* is reflected here automatically — no edits to this file are required.
* @param props - Component props.
* - `expandedAccordion` - Currently open accordion's panel id
* (e.g. `"search-country"`), or `false`.
* - `onAccordionChange` - Factory from panelId to MUI Accordion's
* `onChange` handler.
* @returns The search drawer body (title input, filter accordions, submit).
* @example
* ```tsx
* const [expanded, setExpanded] = useState<string | false>(false);
* const handleChange = (panel: string) => (_e: SyntheticEvent, isOpen: boolean) =>
* setExpanded(isOpen ? panel : false);
*
* <DrawerSearchPanel expandedAccordion={expanded} onAccordionChange={handleChange} />
* // Renders (with current TableColumns config):
* // [Product name or keyword]
* // ▸ Supplier (0 selected)
* // ▸ Country (0 selected)
* // ▸ Shipping Type
* // ▸ Availability
* // ▸ Results Limit (15 per supplier) ← non-column, injected before Price
* // ▸ Price Range
* // [Search]
* ```
