The warning about only sending ERC-20 tokens on the Ethereum network
belongs on the receive page where the QR code is shown, not on the
token detail view. Non-token receive flows hide the warning.
Clicking a token balance on the address detail view navigates to a
focused view showing only that token's transactions. Send pre-selects
and locks the token dropdown, Receive shows an ERC-20 warning for
non-ETH tokens, and all back buttons return to the correct parent view.
