Migrate Dashboard module from hardcoded text to full internationalization
support with Chinese and English translations.

## Changes Made

### Dashboard Components i18n Implementation
- **Dashboard main page** (`index.tsx`): Added i18n for page title, welcome message,
  search button, tab labels, and toast notifications
- **StatsCards** (`stats-cards.tsx`): Implemented i18n for 4 grouped cards with
  8 data metrics (account data, usage stats, resource consumption, performance metrics)
- **Overview** (`overview.tsx`): Added i18n for chart titles, tooltips, and error states
- **ModelUsageChart** (`model-usage-chart.tsx`): Implemented i18n for chart content
  and status messages
- **ModelMonitoringStats** (`model-monitoring-stats.tsx`): Added i18n for monitoring
  statistics cards and descriptions
- **ModelMonitoringTable** (`model-monitoring-table.tsx`): Implemented i18n for table
  headers, pagination, search functionality, and action menus

### Language Files Updates
- **Chinese** (`zh.json`): Added comprehensive Dashboard translations with proper
  key structure and interpolation support
- **English** (`en.json`): Added complete English translations with consistent
  terminology and interpolation variables

### Key Structure Improvements
- Organized i18n keys in logical hierarchy: `dashboard.stats.*`, `dashboard.overview.*`,
  `dashboard.model_usage.*`, `dashboard.monitoring.*`, `dashboard.search.*`
- Added common UI elements to `common.*` namespace for reusability
- Support for interpolation variables (e.g., `{{name}}`, `{{count}}`, `{{percentage}}`)

### Bug Fixes
- **Fixed duplicate JSON keys**: Resolved conflicts between `dashboard.search` (string)
  and `dashboard.search` (object) by renaming to `dashboard.search_button`
- **Fixed duplicate overview keys**: Resolved conflicts between `dashboard.overview`
  (string) and `dashboard.overview` (object) by renaming to `dashboard.overview_tab`
- Updated component references to use corrected i18n keys

### Technical Features
- Full React i18next integration with `useTranslation` hook
- Maintains accessibility standards and semantic HTML structure
- Consistent error handling and loading states across all components
- Support for plural forms and complex interpolation scenarios

## Breaking Changes
None - All changes are additive and maintain backward compatibility.

## Testing
- ✅ JSON validation for both language files
- ✅ No linter errors in Dashboard components
- ✅ No duplicate keys in translation files
- ✅ All i18n keys properly referenced in components

Closes: Dashboard i18n migration task
