feat(meta): per-page titles + favicon/app icons + PWA across the panel

The app had no metadata anywhere — pages showed no <title> and no favicon
or app icon. Added:
- Root metadata in [locale]/layout: title default + "%s — میزی" template,
  description, icons (favicon + apple-touch-icon → /icons), manifest link,
  appleWebApp, themeColor viewport, noindex (private panel).
- Per-page title on all 22 dashboard route pages (داشبورد, منو, گزارش‌ها, …).
- Guest menu (/q) layout: own title + icon + manifest.

PWA + favicon now use the Meezi icon everywhere. Verified via SSR: titles
render (e.g. "منو — میزی") and icon/manifest/apple-touch-icon links present.
