feat(server): network traffic, every interface, CPU threads - #1674
Conversation
… CPU threads - Split the network row into speed and traffic; traffic charts what moved in the range - Device picker lists every interface but loopback - Windows: read cumulative counters instead of rates; totals fall back to every interface when no name matches - CPU row shows the thread count; per-thread bars unfold under the chart Refs #1629

lib/view/page/server/detail/metric_devices.dart (Around line 127)
🟡 Minor 🏗️ Heavy lift
When a server has multiple temperature sensors but its history contains only the aggregate temperature series, the default plotted-device list is empty: _tempSeries returns a single aggregate series labeled “Temperature,” then MetricDevices.of filters that label against sensor names. The live chart therefore falls back to aggregate rendering while the device control reports 0 plotted and the picker opens with every sensor unchecked, contrary to the documented hottest-per-component default and misleading selection state. This occurs with stored/seeded aggregate history plus current per-sensor readings; it would be disproven if those states cannot coexist or if the aggregate series is intentionally treated as a selected sensor.
crates/sbm_parser/src/windows.rs (Around line 77)
🟡 Minor ⚡ Quick win
Windows parse_cpu accumulates per-core pseudo-counters with unchecked u64 addition, so repeated valid 0–100 samples can overflow after enough polls and panic in debug or wrap in release, potentially crashing the status parser/FFI. The summary .sum() can likewise overflow across accepted core values. This is reachable by repeated ordinary CPU polls (and externally supplied prev for public parser API).
lib/data/model/server/time_seq.dart (Around line 120)
🚧 🟡 Minor ⚡ Quick win
A newly appearing interface is reported as a measured 0 B/s instead of unavailable: when eth1 appears in the second sample, _alignPre pairs its current counter with itself, so speedInBytes(device: 'eth1') returns zero even though there is no prior reading for that device. This violates the no-reading distinction and can make device charts/subtitles claim an idle link on first observation. The added test explicitly expects 0, but that expectation masks the missing baseline; the defect would be disproven if a new device were represented as unmeasurable (rather than self-paired).
