Add Phosphor icons; replace sidebar text with hamburger button

- Add phosphor-svelte ^3.1.0 to frontend deps.
- Wire phosphor-svelte/vite (sveltePhosphorOptimize) as a fallback so
  stray named imports still tree-shake correctly. Per-icon imports like
  'phosphor-svelte/lib/ListIcon' remain the preferred pattern; see the
  comment in vite.config.ts.
- Replace the 'Sidebar' text in Header.svelte with a Phosphor List icon
  styled as a square daisyUI button (btn btn-square btn-sm btn-neutral)
  with aria-label preserved for screen readers.
