feat(sprint-2): recursos por actividad — modelo, UX y PDF

Etapas 3-6 del Sprint 2. Resumen de cambios:

**Reporte web (Etapa 3)**
- ActivitiesTable: filas expandibles con desglose fijo + recursos por actividad
- CumulativeSavingsChart: fix payback label superpuesto con eje Y
- BpmnCanvas: badge ⚡ 14→20px
- TECH_DEBT cerrado: chart -inversión (ya estaba), payback label, badge

**Workspace (Etapa 4)**
- WorkspacePage: edición inline de nombre de proceso y cliente
  (click → input → Enter/blur guarda en IndexedDB, checkmark naranja 1.5s)

**PDF (Etapas 5-6)**
- pdf-sections: drawResourcesSection — tabla condicional de recursos por actividad
  con chips de tipo (rol/persona/sistema/equipamiento/insumo)
- pdf-export: página de recursos (pág. 4 cuando hay datos, metodología pasa a pág. 5)
- Fix truncamiento: splitTextToSize en resourceName y top3 ROI
- Fix texto: "ejecución" con tilde, header "Esp. (USD)" sin truncar
- TECH_DEBT cerrado: truncamiento notas metodológicas

**Tests**
- 7 tests nuevos: drawResourcesSection (4) + comportamiento condicional PDF (3)
- Total: 541 → 548 tests verdes

BREAKING: exportScenarioPdf ahora recibe activities[] como parámetro adicional.
