feat: add i18n support for speakers (#204)

## Soporte i18n para ponentes plenarios

Reestructura los datos de speakers para soporte multilingüe, siguiendo
el mismo patrón que `jobs/`.

### Cambios

- `src/data/speakers/es/diego.md` — movido desde `speakers/diego.md`
- `src/data/speakers/en/diego.md` — traducción inglés
- `src/data/speakers/ca/diego.md` — traducción catalán
- `src/components/home/SectionSpeakers.astro` — carga por idioma con
`import.meta.glob` por subdirectorio

### Notas

- `name`, `order`, `photo`, `links` se mantienen iguales en los 3
idiomas
- Solo `description` cambia entre idiomas
- Build verificado: 25 páginas generadas sin errores
