SSO login and settings integration (part 2 of 2)

Depends on #208. Submitted separately following the maintainer's request for the remaining code.

This PR contains only the remaining integration: 3,551 changed lines (3,541 additions + 10 deletions) in 27 files. It is based on current master without the unmerged foundation commits from #208, so the diff stays within the 5,000-line limit. It replaces #209, whose cumulative diff included both parts and was automatically closed for exceeding that limit.

Behavior and scope

Administrators can configure Pocket ID, GitHub.com, or Generic OAuth2, bind an external identity, and enable SSO in Settings. The login page offers the enabled provider and restores the requested local page after sign-in. Existing local sign-in remains available, SSO defaults to disabled, and unbound external identities cannot register or gain administrator access.

• Add public login metadata/start/callback routes and browser-session/CSRF-protected configuration, check, bind, and unbind endpoints.
• Add English/Chinese login and settings UI, callback URL preview/copy, secret preservation, and session-revocation feedback.
• Add Chromium tests for cross-site Strict/Lax cookies, binding, cancellation, login, redirects, CSRF, and revocation, using a local signed OIDC fixture. The E2E command builds web assets before starting the fixture.
• Retry failed login metadata requests at most three times (1s, 2s, 4s), stop after success or page cleanup, and keep local sign-in available. Browser tests cover recovery, retry limits, and cleanup.
• Verify SSO mutations reject another session's matching CSRF cookie/header pair without changing configuration or binding. Document integration handlers and browser flows.
• Add authentication CI, an isolated Docker test setup, and English/Chinese usage, network, session, backup, and rollback documentation.

Dependency and merge order

Merge #208 first, then update this branch from upstream master and merge this PR. The Go integration imports the SSO package and uses auth/store APIs introduced by #208; the redirect tests also use the shared fixture added there. Consequently this branch alone does not yet build or pass all tests until #208 is available. This dependency is intentional so the maintainer can review only the remaining integration now.

The integration remains separate from the foundation changes as requested. Validation combines foundation commit 03d90b0 with this integration branch at 6381376 in a temporary checkout; the two branches merge without conflicts.

Validation

On the combined foundation + integration code:

• Frontend: 40 tests and TypeScript/Vite production build passed.
• go test ./... and go vet ./... passed.
• go test -race ./internal/auth ./internal/store ./internal/server ./internal/sso passed.
• Chromium E2E: all 7 cases passed via npm --prefix web run test:e2e from a checkout with no generated assets.
• Verified the integration-only branch merges with feat(auth): add SSO storage and OAuth2/OIDC foundations (1/2) #208 commit 03d90b0 to exactly the tested tree; git diff --check passed.
• Cross-session CSRF regression test passed; temporarily replacing session-bound CSRF validation with plain authentication made it fail as expected.

Validation used macOS arm64, Go 1.25.14, and Node.js 24. Repeat the relevant checks after bringing in the merged #208 baseline. Real Pocket ID Passkey/access-policy and deployment-network acceptance testing remains required before production use. Schema-29 backup and rollback requirements are described in #208 and the included README updates.

Walkthrough

The change adds SSO authentication with Pocket ID, GitHub, and Generic OAuth2 providers. It adds server endpoints and settings, web configuration and login flows, redirect validation, browser tests, CI coverage, and setup and rollback documentation.

Changes: SSO authentication

Layer / File(s)	Summary
Server setup and SSO settings internal/server/server.go, internal/server/sso_settings.go, cmd/vocat/main.go	The server initializes an SSO service, cleans up expired flows, and registers SSO routes. Settings endpoints validate and save configuration, check saved revisions, and return configuration and binding data. The server write timeout increases to 40 seconds.
SSO authentication and account flows internal/server/sso_auth.go, internal/server/sso_auth_test.go	Handlers add rate-limited login starts, browser-session management, binding and unbinding, callbacks, flow cookies, and audit events. HTTP tests cover provider responses, validation, session behavior, and configuration changes during callbacks.
SSO settings interface and API web/src/types.ts, web/src/api.ts, web/src/lib/sso.ts, web/src/components/settings/SSOCard.tsx, web/src/pages/SettingsPage.tsx, web/src/lib/i18n-en.ts, web/test/ssoSettingsModel.test.mjs	The web app adds SSO data types, API calls, configuration helpers, and an administrator settings card. The card supports provider settings, configuration checks, account binding, and unbinding. Model tests cover configuration and save behavior.
Login entry and safe redirects web/src/lib/safeRedirect.ts, web/src/App.tsx, web/src/pages/LoginPage.tsx, web/test/ssoRedirect.test.mjs	The login page offers SSO when provider metadata reports it enabled and displays callback results. Login redirects use safe-path validation, including for authenticated users who visit the login page.
Browser validation and fixture web/e2e/*, web/playwright.config.ts, web/package.json	A local HTTPS identity-provider fixture and Playwright tests exercise SSO flows and provider metadata retries.
CI, local setup, and documentation .github/workflows/sso.yml, docker-compose.sso-test.yml, .dockerignore, .gitignore, README.md, docs/README.zh-CN.md	CI runs browser, web, and Go checks. Compose supports local testing, ignore rules exclude browser artifacts, and the documentation describes provider setup, network and session behavior, and schema rollback.

The metadata retry behavior works as implemented. Additional HTTP-error coverage would improve regression protection but need not block merging.

Add a cross-session CSRF test for the SSO mutation routes.

78-87: 🔒 Security & Privacy | 🔵 Trivial | ⚡ Quick win

Add a cross-session CSRF test for the SSO mutation routes.

The SSO HTTP tests in internal/server/sso_auth_test.go send only CSRF values from the request's own session. No test sends a matching cookie and header pair from a different session. Removing the ValidateCSRF call in requireBrowserSession (internal/server/sso_auth.go:80) would not change any test result.

Add a case that sends a second session's matching cookie and header. Expect 403 invalid_csrf and unchanged SSO settings and bindings for PUT /api/settings/sso, POST /api/auth/sso/bind, and DELETE /api/auth/sso/binding.

Add an HTTP 503 case to the provider metadata retry tests.

321-325: Trivial · Maintainability & Code Quality · Quick win

Add an HTTP 503 case to the provider metadata retry tests.

LoginPage retries any rejected getSSOProviders() call, and api() throws ApiError for a 503 response. The existing metadata tests simulate failures only with route.abort(). A change that retries only network errors would still pass them. A test that returns HTTP 503 before the successful response covers the status-based retry path.

Suggested test

   await expect(page.getByRole("link", { name: "Continue with Recovered provider", exact: true })).toBeVisible();
   await page.clock.fastForward(30_000);
   expect(attempts).toBe(2);
 });

Review comment at @web/e2e/sso.spec.ts around lines 321 - 325:
Add a provider metadata retry test in the existing `LoginPage` tests that
returns HTTP 503 on the first `**/api/auth/providers` request and a successful
provider response on the next. Verify the retry occurs and the recovered
provider link becomes visible, covering status-based rejection rather than only
`route.abort()` network failures.
