feat(i18n): add consolidated translation keys for strategy components

[xsa-dev]

Summary

This PR adds 275+ consolidated translation keys for 8 strategy components, supporting 3 languages (en, zh, es).

What This PR Does

1. Creates web/src/i18n/strategy-translations.ts with:

   • 8 translation sections (coinSource, gridConfig, gridRisk, riskControl, promptSections, indicator, publishSettings, chartTabs)
   • All keys in en + zh + es
   • Pre-aggregated exports: zhStrategy, enStrategy, esStrategy

2. Purpose: Centralize scattered i18n strings currently inline in 8 component files

Why This Matters

Current Problem: 8 components use scattered { zh: '...', en: '...' } pattern:

// Current anti-pattern in 8 files
const labels = {
  key: { zh: '中文', en: 'English' },
}
{t('key')[language]}

Solution: Centralized translations:

// NEW: Use centralized t('key', language)
import { coinSource } from 'i18n/strategy-translations'
t(coinSource.sourceType, language)

Components to Migrate (Future Work)

Component	Current Pattern	Status
CoinSourceEditor.tsx	{ zh, en } objects	Ready for migration
GridRiskPanel.tsx	{ zh, en } objects	Ready for migration
RiskControlEditor.tsx	{ zh, en } objects	Ready for migration
GridConfigEditor.tsx	{ zh, en } objects	Ready for migration
PromptSectionsEditor.tsx	{ zh, en } objects	Ready for migration
IndicatorEditor.tsx	{ zh, en } objects	Ready for migration
PublishSettingsEditor.tsx	{ zh, en } objects	Ready for migration
ChartTabs.tsx	{ zh, en } objects	Ready for migration

Hi @tangmengqiu and @hzb1115!

This PR is blocking the i18n refactor for 8 strategy components. Once merged, we can proceed with migrating:

• CoinSourceEditor.tsx
• GridRiskPanel.tsx
• RiskControlEditor.tsx
• GridConfigEditor.tsx
• PromptSectionsEditor.tsx
• IndicatorEditor.tsx
• PublishSettingsEditor.tsx
• ChartTabs.tsx

The consolidation file is ready and tested. Could you please review and merge when convenient?

Thank you!
