feat: translate final sections of Law10Tab (summary table and data maturity)

Completed Spanish-to-English translation of Law10Tab by:
- Translating summary table headers (Requisito, Estado, Score, Gap, Descripción)
- Translating legend labels (Cumple, Parcial, No Cumple, Sin Datos)
- Translating investment section (Coste de no cumplimiento, etc.)
- Translating DataMaturitySummary title and sections
- Translating all data items (Cobertura temporal 24/7, etc.)
- Translating investment phases (Fase 1, Fase 2)
- Translating totals section

Added new translation keys:
- law10.summaryTable.* (table headers, legend, investment)
- law10.dataMaturity.* (title, sections, items, investment phases)

All Law10Tab sections now fully support English translation.
