CLAUDE: Fix stale injury records blocking /injury set-new

Added data consistency check to automatically clear stale injury records
where is_active=True but il_return=None. This prevents old injury records
from blocking new injury creation when players should not be injured.

- Detects mismatch between injury table and player il_return field
- Auto-clears stale injury records with warning log
- Allows legitimate injuries with matching il_return to block command
- Logs both warning (stale data found) and info (cleared) for debugging

Fixes issue where Ronald Acuna Jr had active injury record but no il_return.
