feat: causal lab - delete template + observable mapping + edge editing

- TabLibrary: bouton Supprimer (templates user uniquement)
- TabEditor: inputMapping dans EditorState, panneau mapping visible quand noeud observable selectionne
- TabEditor: edition d aretes (cliquer sur arête pour modifier style/force/signe/label)
- Backend: GET /api/causal-lab/data-sources (prices/macro_series/ff_events)
- analyze: auto-fetch market_watchlist+economic_events+ff_calendar depuis input_mapping
- TabAnalyze: affiche inputs auto-recuperes vs manuels dans les resultats
