fix: use formatAddressHtml in receive view for display consistency

The receive view was using raw textContent and a manually constructed
color dot instead of the shared formatAddressHtml helper used by other
views. This violated the display consistency policy ('Same data
formatted identically across all screens').

Changes:
- Use formatAddressHtml() to render address with color dot, title
  (e.g. 'Wallet 1 — Address 1'), and ENS name — matching addressDetail
- Make the address block itself click-to-copy (matching policy:
  'Clicking any address copies the full untruncated value')
- Replace separate receive-dot/receive-address spans with a single
  receive-address-block element
- Address is still shown in full (no truncation) as appropriate for
  the receive view

Closes #58
