[FIX] 徹底修復商品管理分頁參數洩漏與 UI 狀態不一致問題

1. 隔離商品列表與分類管理的搜尋參數（product_search / category_search）。
2. 隔離商品列表與分類管理的公司篩選參數（product_company_id / category_company_id）。
3. 優化分頁切換邏輯，切換 Tab 時自動清理 URL 參數，解決標籤殘留問題。
4. 修復 searchable-select 組件因屬性傳遞錯誤導致的 500 Internal Server Error。
5. 統一各分頁「公司篩選」Placeholder 為「所有公司」。
6. 完成分類管理搜尋框的多語系支援（新增 Search categories... 翻譯鍵值）。
7. 優化分頁器 (Pagination) 樣式以符合極簡奢華風規範。
