fix a stack overflow in the wallet copy button

Mine, from the clipboard sweep. format.ts exported copyToClipboard wrapping
navigator.clipboard; the sweep replaced the body call with copyToClipboard(value),
so the function called itself. CopyField.tsx is the caller, so every copy button in
the Wallet was an infinite recursion.

Removed the wrapper rather than repointing it — helpers/clipboard already does more
(execCommand fallback on an insecure origin) and CopyField imports it directly now.

Found by finally running tsgo, in the officerdev-test tree, which has node_modules.
