Render the landing page without a Base44 session

LandingPage is pure marketing markup — no entity reads, no useAuth — but it sat
below both gates in AuthenticatedApp, so anonymous visitors were held on the
spinner for a bootstrap round-trip and then redirected to Google before they
could read anything about the product.

Check the path against a PUBLIC_ROUTES set first and return early. Its CTAs
still point at /Dashboard, which stays gated, so signing in is one click away.

Drops the old /LandingPage block that sat below the auth gate; the early return
makes it unreachable, as the previous ordering already did.
