feat: enrichers, panel de ingest y menu contextual en el grafo

- Añade enricher.go + directorio enrichers/ para enriquecer entidades con fuentes externas.
- Nuevos componentes frontend: IngestPanel (panel de ingesta de datos) y NodeContextMenu (menu contextual sobre nodos del grafo).
- Retira SearchBar y lib/utils.ts; la busqueda se integra dentro de los paneles existentes.
- Ajusta tipos (types.go, types.ts, wailsjs/go) y theming (postcss + app.css + Mantine).
- Actualiza app.go y wails.json para exponer las nuevas capacidades.
- Añade directorio projects/ con estado inicial.
- Rebuild del frontend (dist actualizado).
