feat: partial translation of AgenticReadinessTab (phase 1)

Translated initial ~86 strings in AgenticReadinessTab:
- Converted FACTOR_CONFIGS to getFactorConfigs(t) function
- Updated getTierStyle() to accept t parameter
- Updated ScoreBreakdownTooltip component with translations
- Translated AgenticMethodologyIntro component completely
- Added click-outside functionality to methodology modal

New translation keys added to agenticReadiness section:
- methodology.* (title, subtitle, definition, factors, categories)
- factorConfigs.* (detailed factor descriptions)
- scoreBreakdown.* (factor labels)
- tiers.* (tier action labels)

Remaining work in progress: ~264 strings being translated by background agent
