docs(privacy): tell users about the IP surfaces (mints, directions, AI) + surface it where it matters

- /privacy IP section now lists Cashu mints, directions (OSRM/Transitous receive
  the route endpoints), and Sasquatch AI — and states the sharp bit: a relay can
  link your IP to your pubkey ('this person, from this address').
- Corrects the old 'none of these receive your GPS location' claim, which stopped
  being true once directions shipped (they get your origin/destination).
- Notes the one we DO shield: the mints directory is proxied through our server,
  so MintRadar never sees the user's IP.
- Removes the named VPN brand; copy is now neutral ('use one you pay for and
  trust; treat free as a warning sign').
- Settings -> Relays gets a one-line privacy note linking to /privacy.
