feat: enhance codexlens frontend integration with reranker config, MCP tools card, and LSP management

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
