fix: unify handler response format in log, permission, webhook handlers

- log_handler.go: Fix GetMyLoginLogs/GetMyOperationLogs/GetLoginLogs/GetOperationLogs to use {code, message, data}
- permission_handler.go: Fix all error responses to use {code, message}
- webhook_handler.go: Add missing "message" field in success responses, wrap data in data object with list/total/page/page_size
- webhook_handler_test.go: Update test to match new response format

Standardize all JSON responses to {code: 0, message: "success", data: ...} for success
and {code: XXX, message: "..."} for errors.
