fix: break circular import in horse racing commands
Extract shared.py from commands/__init__.py to break circular dependency: - shared.py: shared variables/services/helper functions - access.py: get_scope/check_access/get_event_id (canonical source) - __init__.py: re-exports from shared.py for backward compat - register/bet/race/help: import from .shared instead of package
