[FEAT] 主控台 UI 全面翻新 (Console UI Overhaul)

1. MainActivity.java：重構按鈕點擊邏輯，改用 Lambda 取代匿名 Runnable；新增 activeLoginDialog 追蹤機制，登入成功後自動關閉對話框並呼叫 updateLoginStatus()；新增頂部登入/登出狀態按鈕 (btnStatusAction) 切換邏輯。
2. activity_main.xml：全面翻新 UI 佈局，導入卡片式分組選單、現代化 Header 區塊（含 Logo、版本號、機台狀態）、功能按鈕網格排版，以及底部版權列。
3. colors.xml：建立完整 Material 3 色彩系統，包含 primary/secondary/surface/background 色階，以及 success/warning/error/info 四種語意狀態色；調整 black 為深灰 (#272727)。
4. dimens.xml：新增 welcome 標題、Header Logo、選單按鈕圖示及間距等全套尺寸規格變數。
5. 新增三個 Drawable 資源：bg_button_primary.xml (主要按鈕樣式)、bg_button_outline.xml (外框按鈕樣式)、bg_input_modern.xml (現代化輸入框背景)。
6. 新增 values-sw720dp/dimens.xml：針對 720dp 以上大螢幕（10吋機台）的適配尺寸規格。
7. 新增主控台各功能示意圖資源（drawable/*.png）：binding_machine、card_reader_checkout、card_reader_reboot、cargo_lane_management、product_list、reboot_app、sales_page、scanner_test、system_settings、taiwan_star_tech_logo、view_log_records、vending_machine_scenario_v1/v2。
8. app/build.gradle：verPatch 從 1 升至 6，對應本次多功能迭代開發。
9. dialog_admin_login.xml：新增獨立的管理員登入對話框佈局。
