Add auth UI: login/register pages, OIDC button, route guard (#6)

Frontend for pansy auth, rendering whatever /auth/providers reports.

- lib/auth.ts: zod-validated User/Providers, a shared meQueryOptions
  (a 401 resolves to null, not an error) reused by useMe() and the router
  guard, useProviders(), and useLogin/useRegister/useLogout mutations that
  prime/clear the me cache (logout also drops non-auth cached data).
- lib/queryClient.ts: one QueryClient shared by the React tree and the
  router context so guard and components hit the same cache.
- router.tsx: createRootRouteWithContext with the queryClient; requireAuth
  (redirects to /login?redirect=<dest>) on gardens/plants/editor, and
  requireGuest on login/register (bounces authed users away). Login search
  params (redirect, error) validated as optional; redirect targets are
  restricted to same-origin paths.
- pages/LoginPage: OIDC button (label from providers) linking to
  /auth/oidc/login, "or" divider, local email/password form, and friendly
  messages for the OIDC callback ?error= codes. RegisterPage: email +
  display name + password (min 8), registration-closed and SSO-only
  handling; auto-login lands on /gardens.
- AppShell: auth-aware nav — shows the user's display name + Sign out when
  logged in, Sign in otherwise; nav links only when authed.
- ui/: TextField (16px text to avoid iOS zoom, autocomplete + a11y),
  Button (+ shared buttonClasses for the OIDC anchor), Alert; AuthCard.

Verified in a real browser against the embedded binary: register →
auto-login → /gardens; refresh stays in; Sign out → /login; a logged-out
/gardens/1 redirects to /login and returns after login; OIDC button renders
with the Authentik label when configured. tsc --noEmit clean.
