[_]: refactor/enhance error logging with request IDs

[jzunigax2]

• Add ErrorUtils.getRequestId/withRequestId helpers to consistently extract a request ID (from requestId, xRequestId, or a nested data.requestId) and append it to log messages.
• Wire these helpers into WebDAV startup/uncaught-exception logging, the auth and error-handling middlewares, the PUT handler's replace-fallback log, and DriveItemService's UUID/path lookup fallbacks, so request IDs are consistently surfaced for debugging.
• Add ErrorUtils.isNotFoundError and use it to suppress noisy warnings when a lookup fails simply because the item doesn't exist (404), only logging unexpected lookup errors.
• Switch DriveItemService from the generic logger to webdavLogger for consistency with the rest of the WebDAV module.
• Add test coverage for the new errors.utils helpers, the PUT handler fallback logging, the errors middleware, and the drive-item service lookup logging.
