fix(telemetry): add missing exit codes to explain_exit_code()

- Add curl error codes: 4, 5, 8, 23, 25, 30, 56, 78
- Add code 10: Docker/privileged mode required (used in ~15 scripts)
- Add code 75: Temporary failure (retry later)
- Add BSD sysexits.h codes: 64-77
- Sync error_handler.func fallback with canonical api.func
