Implements public Cardano address directory using Matrix account data:
Publishing (write side):
- After wallet creation, import, or SSSS restore, the Cardano address
is written to the user Matrix account data
- Key: com.sulkta.cardano.address
- Content: { "address": "addr1..." }
- This is public/unencrypted for discovery by other users
Lookup (read side):
- When entering a Matrix user in /pay, their account data is checked
- If they have a linked Cardano address, it auto-fills the recipient
- UI shows "Address loaded from @username profile ✓" when found
- Shows "@username has not linked a wallet" if not found
- Graceful fallback to manual address entry
New files:
- CardanoAddressService interface (wallet:api)
- DefaultCardanoAddressService implementation (wallet:impl)
Updated:
- WalletSetupPresenter: calls publishAddress after all wallet setup paths
- PaymentEntryPresenter: looks up recipient address from Matrix
- PaymentEntryState: added Resolving and Found states
- PaymentEntryView: shows lookup progress and result cards
