feat(14-01): create auth_components.templ and auth_layout.templ

- auth_components.templ: AnimatedBackground (35 elements, /static/logo_dark.png, no light/dark pairs), GoogleButton (a/button variant, English label 'Sign in with Google'), AuthDivider ('or' divider)
- auth_layout.templ: standalone HTML shell with .login-screen, @AnimatedBackground(), .card-wrap/.card-glow/.auth-card-shell, htmx.min.js only (no sortable/sse scripts)
- No auth.User param on AuthLayout (auth pages always unauthenticated)
- just generate exits 0, all Go tests pass

// AnimatedBackground renders 35 decorative logo elements that animate across
// the auth page background. The .background-layer carries aria-hidden="true"
// so screen readers ignore all decorative content (T-14-01-03).
//
// Each element uses a single logo_dark.png image (dark-mode swap deferred per
// DEFERRED/DARK-01). Image paths use /static/logo_dark.png — backend serves
// static files under /static/ unlike go-backend which serves from /.

// AuthLayout is the standalone HTML shell for auth pages (/login, /signup).
//
// It replaces @Layout(...) for these pages. Differences from Layout:
// - No header, footer, or <main> wrapper — auth pages are full-viewport centered
// - Body uses .login-screen (gradient bg, flex center) instead of min-h-screen bg-white
// - @AnimatedBackground() renders 35 animated logo elements behind the card
// - No auth.User param — auth pages are always unauthenticated (T-14-01-04)
// - Scripts: only htmx.min.js — sortable.min.js and discussion-sse.js are not needed
//
// csrfToken is threaded so page children (LoginPage, SignupPage) can forward it
// into their form fragments via ui.CSRFField(csrfToken). AuthLayout itself does
// not embed a CSRF field — only the form fragments do.
