CLAUDE: Fix player drops going to wrong team (DENIL id 503 instead of FA id 498)

Fixed critical bug where player drops/releases were assigned to team id 503 (DENIL)
instead of the correct Free Agency team (id 498). The transaction_builder.py had
a hardcoded team ID instead of using the config value.

**Root Cause:**
- Line 446 in services/transaction_builder.py hardcoded `id=503` for Free Agency
- Correct Free Agency team ID is 498 (from config.free_agent_team_id)
- Team 503 is DENIL, causing dropped players to appear on wrong roster

**Fix:**
- Changed to use `config.free_agent_team_id` (498) dynamically
- All drop/release transactions now correctly target Free Agency

**Affected Players in Production:**
- Luis Torrens, Jake Meyers, Lance Lynn, Seranthony Dominguez
- These players need manual correction in production database

**Testing:**
- All 31 transaction_builder tests pass
- Validates correct team assignment for drop operations
