Supervisor S-0c: Log Viewer im Terminal (JSONL menschenlesbar, CID-Forensik)

Browse Source 
Terminal-Fenster jetzt mit TabControl (via Designer): Tab 'Live' = bisherige Anzeige,
Tab 'Log Viewer' = JSONL-Tagesdateien menschenlesbar aufbereitet:
- Filter: Datum (DateTimePicker), Level, CorrelationId (SignalId), Suchtext.
- Doppelklick auf eine CID laedt die komplette Signal-Kette ('zeig mir alles zu diesem Signal').
- LogJson.ParseLine (pur, Gegenstueck zu Format): tolerant gegen kaputte Zeilen (null statt Crash);
  Viewer ueberspringt sie. UI-Schutz bei sehr grossen Tagen (20k-Limit).

Tests: +5 (Parse-Roundtrip, kaputte Zeilen). Build 0 Fehler, 341 Tests gruen, --smoke-ui komplett gruen.
