Adds a pre-login public store locator (guest session via DeviceCheck/App
Attest, keychain-backed token storage) so the app no longer forces sign-in
before showing any content, plus updated support URL metadata.
Terms and Privacy screens now fetch the real PediFoods customer PDFs
from the backend instead of showing static placeholder text. Also
surfaces both links on the Profile screen below the version label,
not just during registration.
