feat: Persist settings via agent-server REST API with server-side merge

AGENTS.md

   - For local verification in this repo, setting `VITE_WORKING_DIR=/workspace/project/agent-server-gui` avoids initial Changes-tab 500s from pointing conversations at the non-repo parent `/workspace/project`.
   - A successful end-to-end live run in this environment required a real LLM config (`LLM_MODEL` + `LLM_API_KEY`). The default `litellm_proxy/...` model with no `llm_api_key` failed at runtime with a `litellm.AuthenticationError`.
 
-- Agent-server recovery UX gotchas:
-  - Keep `/settings/agent-server` in the intermediate-page bypass path (`use-is-on-intermediate-page`) so `useConfig()`-driven layout/sidebar queries do not block the recovery screen behind a global spinner.
-  - `PostHogWrapper` should treat config-fetch failures as silent/optional (no user-facing toast), otherwise onboarding/recovery screens show a duplicate incompatible-server toast on top of the friendly guidance.
-  - Keep the settings route on the compact `AgentServerConnectionForm` variant with `showSectionHeader={false}` and no checklist; the blocked root onboarding should stay similarly minimal, with only the status card plus a single sentence that links to the repo setup instructions.
-  - For local screenshot/GIF capture of SPA routes, serve `build/` with an SPA fallback (for example `sirv build --single`) and restart the static server after each rebuild so hashed asset URLs stay in sync.
-
-- Git provider token persistence note: this direct-agent-server frontend now persists `Settings > Git` provider tokens locally in browser storage instead of posting to an app-backend secrets route. `src/api/secrets-service.ts` writes the token payload to localStorage, mirrors provider hosts into `provider_tokens_set` through `SettingsService.saveSettings()`, and `use-delete-git-providers` clears that local state.
+- **Settings persistence architecture**: Settings are now persisted via the agent-server REST API (`/api/settings` endpoints) instead of relying solely on localStorage. The `SettingsService` in `src/api/settings-service/settings-service.api.ts` uses the `@openhands/typescript-client` `SettingsClient` for CRUD operations:
+  - `getSettings()` fetches from the agent-server with localStorage as fallback
+  - `saveSettings()` posts diffs to the server and updates the local cache
+  - The local cache key `openhands-agent-server-settings` remains for offline scenarios and faster initial loads
+  - The agent-server persists settings to `~/.openhands/settings.json` on disk
+- **Secrets persistence**: Custom secrets (`Settings > Secrets`) are now managed via the agent-server's `SettingsClient.createSecret()`, `listSecrets()`, `deleteSecret()` methods. The server encrypts API keys using the SDK's Cipher utility and stores them at `~/.openhands/secrets.json`.
+- Git provider token persistence note: this direct-agent-server frontend still persists `Settings > Git` provider tokens locally in browser storage (`openhands-agent-server-git-provider-tokens`) while mirroring host metadata into settings via `SettingsService.saveSettings()`.
 - Agent server connection settings now live at `Settings > Agent Server` (`/settings/agent-server`). The page reads deployment defaults from `VITE_BACKEND_BASE_URL` / `VITE_SESSION_API_KEY`, saves user overrides in the `openhands-agent-server-config` localStorage key, and must stay reachable even when the backend compatibility probe fails so users can recover from missing or wrong backend configuration.
 
 - README expectation: keep the first section as a concrete, chronological from-scratch quickstart for running this frontend against a real `openhands-agent-server` (clone, install backend, optional `.env`, run `npm run dev`).
