feat: complete translation of remaining Spanish strings in Law10Tab and RoadmapTab

Law10Tab changes:
- Fixed 3 Spanish time unit abbreviations (año→yr, mes→mo)
- Changed "65K/año" to "65K/yr" (line 1444)
- Changed "35K + 8K/mes" to "35K + 8K/mo" (line 1448)
- Changed "12-18K/año" to "12-18K/yr" (line 1452)

RoadmapTab changes (41 strings translated):
- Translated DECISION_GATES object (18 keys) - converted to getDecisionGates(t) function
- Translated timeline title and description (2 keys)
- Translated all payback tooltip texts (5 keys)
- Translated wave descriptions and recommendations (12 keys)
- Translated scenario comparison texts (4 keys)
- Added useTranslation() hook to RoadmapTimeline component
- Updated recommendation generation to use t() with interpolation

Translation keys added:
- roadmap.payback.* (5 new keys)
- roadmap.decisionGates.* (12 keys)
- roadmap.timeline.* (2 keys)
- roadmap.specificRecommendations.* (12 keys)
- roadmap.scenarios.* (3 keys)
- roadmap.wave2Description.* (2 keys)

All components now fully support Spanish-English translation switching.
