Fix sWAR cap validation for /ilmove and /dropadd commands

- Add sWAR cap validation to TransactionBuilder.validate_transaction()
- Use team-specific salary_cap from Team.salary_cap field
- Fall back to config.swar_cap_limit (32.0) if team has no custom cap
- Add major_league_swar_cap field to RosterValidationResult
- Update major_league_swar_status to show ✅/❌ with cap limit
- Add 4 new tests for sWAR cap validation

This fixes a bug where IL moves could put a team over their sWAR cap
because the validation only checked roster counts, not sWAR limits.
