feat: display zap recipient username in all contexts (#147)

* feat: display zap recipient username in all contexts

- Add recipient username display for profile zaps
- Show recipient after amount in compact preview
- Show recipient with arrow (→) in full zap receipt renderer
- Fixes missing context when zaps don't target specific events

* refactor: remove arrow from zap recipient display
