fix(ui): report category dropdown uses folds menu, not native select (N56)

Extract a shared ReportCategorySelect: folds Button trigger + PopOut +
FocusTrap + Menu + MenuItem (escape + arrow-key nav, like OrderButton),
replacing the OS-styled native <select> in both ReportRoomModal and
ReportUserModal.

 **N56 — Report Modal Category Dropdown: Native `<select>` Instead of folds `Chip`+`PopOut`+`Menu`**
 
 - **File:** `src/app/features/room/ReportRoomModal.tsx` lines 138–163; `src/app/features/room/ReportUserModal.tsx` lines 144–169
-- **Status:** **OPEN**
+- **Status:** **FIXED** — extracted a shared `ReportCategorySelect` component (`src/app/features/room/ReportCategorySelect.tsx`) using the folds `Button` trigger + `PopOut` + `FocusTrap` + `Menu` + `MenuItem` pattern (with `escapeDeactivates`/arrow-key nav, matching `OrderButton`); both modals now use it instead of the native `<select>`.
 - **Issue:** Both report modals render the "Category" field as `<Box as="select">` with hand-rolled inline styles (padding, border, background, color, fontSize, fontFamily). No other selector in the message-action modal context uses `<select>` — the established pattern for all dropdowns in both message modals and search filters is `Chip onClick → setMenuAnchor → PopOut → FocusTrap → Menu → MenuItem` (reference: `OrderButton` in `SearchFilters.tsx` lines 63–114).
-- **Fix:** Replace native `<select>` with `<Chip>` trigger + `<PopOut>` + `<Menu>` + `<MenuItem>` pattern.
