feat: Add Team API for cross-device persistence

- GET /api/team - get user's battle team
- POST /api/team - set entire team (max 3)
- PATCH /api/team/heal - heal all team members
- PATCH /api/team/:pokemonId - update HP after battle
- DELETE /api/team/:pokemonId - remove from team

- Added team API methods to client.js
- Created D1 migration for team table
- Migration executed on remote DB

All 180 tests passing
