Add three integration improvements to the CodexLens management panel:
- Enhance SettingsTab with RerankerConfigCard using /reranker/config endpoint
for dynamic backend/model/provider dropdowns
- Add CcwToolsCard to AdvancedTab showing CCW registered tools with
codex-lens tools highlighted
- Add LspServerCard to OverviewTab with start/stop/restart controls
mirroring the FileWatcherCard pattern
- Create LSP lifecycle backend endpoints (start/stop/restart) bridging
to Python StandaloneLspManager
- Add corresponding TanStack Query hooks, API functions, and i18n keys
