Implement DOGE refund support in crypto payment rescue

- Add coin-specific refund logic (XMR uses transfer, DOGE uses sendtoaddress)
- Fix confirmation threshold logging to use coin-specific requirements
- Improve refund amount logging to show correct coin type and atomic units
- DOGE refunds now use sendtoaddress RPC instead of failing with 404

Note: Crypto watcher needs restart to pick up changes
