refactor: Consolidate scattered imports to top of service files

Browse Source 
Moved imports from middle of files to the top for better code organization.

Changes:
- Moved csv, io, peewee, playhouse imports to top of player_service.py
- Moved playhouse import to top of team_service.py
- Kept lazy DB imports (Player, Team, db) in methods where needed
  with clear "Lazy import" comments explaining why

Rationale for remaining mid-file imports:
- Player/Team/db imports are lazy-loaded to avoid importing heavyweight
  db_engine module during testing with mocks
- Only imported when RealRepository methods are actually called
- Prevents circular import issues and unnecessary DB connections in tests

All tests pass: 76 passed, 9 skipped, 0 failed
