fix(openclaw): address code review findings across P0-P3 issues

- Add 25 missing i18n keys for OpenClawFormFields in all 3 locales (P0)
- Replace key={index} with stable crypto.randomUUID() keys in EnvPanel,
  ToolsPanel, and OpenClawFormFields to prevent list state bugs (P1)
- Exclude openclaw from ProxyToggle/FailoverToggle in App.tsx (P1)
- Add merge_additive_config() for openclaw/opencode deep link imports (P1)
- Normalize serde(flatten) field naming to `extra` + HashMap (P2)
- Add directory existence check in remove_openclaw_provider_from_live (P2)
- Remove dead code in import_default_config and openclaw API methods (P2)
- Add duplicate key validation in EnvPanel before save (P2)
- Add openclawConfigDir to Settings type (P2)
- Add staleTime to OpenClaw query hooks (P3)
- Fix type-unsafe delete via destructuring in mutations.ts (P3)
