- feat:新增附件列表管理和增加按钮提示

Introduce an upload attachments panel with styles, localization and client-side management. Added new i18n keys (EN/ZH) and refactored js/i18n.js to helper setters for text/placeholder/title. popup.html and css/main.css add the upload-list UI and styles. oper.js implements rendering, drag-and-drop reorder, deletion (calls DELETE api with token), storage persistence (resourceIdList), escapeHtml sanitization, and sync change handling; it also fixes a config check (repo -> apiTokens), stores filename from upload responses, handles attachments/resources compatibility, and clears the list after sending a memo. Overall this enables reorderable, deletable uploaded attachments with proper localization and tooltips.
