* feat: Implement provider groupings with account calculator and comprehensive fixes

- Add provider detection utilities (detectProvider, PROVIDER_REGISTRY) for Claude/Gemini/Others categorization
- Implement grouping logic (groupModelsByProvider, calculateProviderStats, calculateAccountStats) with health status calculation
- Create useProviderGrouping hook for collapsible state management and persistence
- Add ProviderGroup component with health indicators, progress bars, and model visibility integration
- Enhance CloudAccountList with account-level calculator showing overall percentage and earliest reset time
- Implement grid layout selector (auto/2-col/3-col/list) with config persistence and tooltips
- Add global quota aggregate bar across all accounts in top statistics
- Fix model visibility settings regression by accessing account.quota.models instead of account.quota
- Show 'Rate Limited' instead of '0%' for exhausted quotas with consistent getQuotaLabel function
- Add comprehensive i18n translations for layout selector and rate limited labels (en, zh-CN, ru)
- Disable batch operations when provider groupings are enabled to prevent conflicts
- Include unit tests for provider detection logic and grouping functionality

Addresses critical issues: model list regression, rate limited display, layout control, global quota visibility, and consistent quota labeling across all components.

* fix: resolve ESLint no-ex-assign violations in proxy service

- Fix exception parameter reassignment in catch blocks
- Rename catch parameters to avoid no-ex-assign rule violations
- Maintain same error handling logic while complying with linting rules

* fix: add missing Models tab to settings page

- Add Models tab between General and Proxy tabs
- Import and integrate ModelVisibilitySettings component
- Fix critical regression where model visibility settings were inaccessible

* fix: add missing React hook imports in settings route

* test: remove obsolete tests for removed controller APIs
