docs(swagger): 補全缺漏端點標註 + 更新 README 文件 URL

新增 11 個先前缺漏的 @OA 標註：
- Token Refresh（Member / Provider / Admin）
- Provider 資格驗證申請（show / upload / delete cert / submit）
- 即時訊息聊天室（unread-counts / list / send / mark-read）

其他：
- l5-swagger.php 標題改為 CFDive Platform API
- README 補充 Swagger UI URL 與 JSON 端點位置
