[STYLE] 修復機台庫存管理功能並全面升級極簡奢華風 UI

1. [FIX] 修復 MachineController 500 錯誤：注入缺失的 MachineService 執行個體。
2. [STYLE] 貨道卡片重構：改為垂直堆疊佈局，移除冗餘標籤，並優化庫存 (x/y) 與效期格式。
3. [STYLE] 極致化間距調優：壓縮全域 Padding 與 Gap，並將貨道編號絕對定位於頂部，提升顯示密度。
4. [FIX] 穩定性修復：解決 Alpine.js 在返回列表時的 selectedMachine 空值存取報錯。
5. [STYLE] UI 細節修飾：隱藏輸入框微調箭頭，強化編號字體粗細與位置精準度。
6. [DOCS] 翻譯同步：更新 zh_TW, en, ja 翻譯檔中關於庫存與貨道的語系 Key。
7. [FEAT] 整合遠端管理模組：新增並導航至 resources/views/admin/remote/stock.blade.php。
