Do not map generic log-fetch failures to 404.
stream_logs() returns false for any unsuccessful gRPC status, including transport or backend failures, without updating last_error_. Client.logs() then falls back to "failed to fetch logs" when no error text is available. _fetch_solver_logs maps that generic text to _log_not_found(job_id), which can turn an operational failure into HTTP 404.

‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.
