CLAUDE: Refactor draft system to eliminate hard-coded magic numbers

Browse Source 
Replace all hard-coded values with centralized config constants for better
maintainability and flexibility:

Added config constants:
- draft_team_count (16)
- draft_linear_rounds (10)
- swar_cap_limit (32.00)
- cap_player_count (26)
- draft_total_picks property (derived: rounds × teams)

Critical fixes:
- FA team ID (498) now uses config.free_agent_team_id in:
  * tasks/draft_monitor.py - Auto-draft validation
  * commands/draft/picks.py - Pick validation and autocomplete
- sWAR cap limit display now uses config.swar_cap_limit

Refactored modules:
- utils/draft_helpers.py - All calculation functions
- services/draft_service.py - Pick advancement logic
- views/draft_views.py - Display formatting

Benefits:
- Eliminates risk of silent failures from hard-coded IDs
- Centralizes all draft constants in one location
- Enables easy draft format changes via config
- Improves testability with mockable config
- Zero breaking changes - fully backwards compatible
