Subject: [PATCH] Fix crash on load when no wallet extension is installed

InstallSnap read window.ethereum.networkVersion unguarded; on any browser
without MetaMask (all mobile) this threw and took down the whole page with
"Application error: a client-side exception has occurred". NavBar renders
InstallSnap on every page, so the site was unusable without a wallet.

Guard the accesses with optional chaining - without a wallet the OR Snap
button now renders disabled instead of crashing.
