fix: handle both scheduled and immediate execution in Warrior ShieldBash test

- Force character to be Warrior class to avoid test flakiness
- Accept both scheduled task and immediate execution as valid outcomes
- Abilities may execute immediately (address(1)) or be scheduled as tasks
- This prevents CI failures when abilities are executed immediately
