fix: translate remaining Spanish text in RoadmapTab priority queues section

- Add translation keys for ENTRADA/SALIDA labels
- Add translation keys for Tier:/Score: labels
- Replace hardcoded Spanish strings with t() calls:
  * "ENTRADA" → t('roadmap.table.entry')
  * "SALIDA" → t('roadmap.table.exit')
  * "Tier:" → t('roadmap.table.tierLabel')
  * "Score:" → t('roadmap.table.scoreLabel')
  * "Top Colas por Volumen × Impacto" → t('roadmap.table.topQueuesByVolumeImpact')
  * Red Flags note → t('roadmap.table.redFlagsNote')
  * "Skills" → t('roadmap.table.skills')

All content under "Oportunidades Priorizadas" section now fully translated.
