fix: align receive view address display with addressDetail pattern

The receive view was using formatAddressHtml() which rendered addresses
with a different structure (bold title label above address) compared to
addressDetail's pattern (separate dot + full address + etherscan link
inline elements). This violated the display consistency policy.

Now uses the same element structure as addressDetail: separate
receive-address-dot, receive-address-full, and receive-etherscan-link
spans, with ENS name shown in a separate element matching addressDetail.

Closes #58
