fix(tenancy): fix team CRUD bugs + add member integration tests

Store team page:
- Fix undefined user_id (API returns `id`, JS used `user_id`)
- Fix wrong URL path in updateMember (remove redundant storeCode)
- Fix update_member_role route passing wrong kwarg (new_role_id → new_role_name)
- Add update_member() service method for role_id + is_active updates
- Add :selected binding for role pre-selection in edit modal

Merchant team page:
- Add missing db.commit() on invite, update, and remove endpoints
- Fix forward-reference string type annotation on MerchantTeamInvite
- Add :selected binding for role pre-selection in edit modal

Shared fixes:
- Replace removed subscription_service.check_team_limit with usage_service
- Replace removed subscription_service.get_current_tier in email service
- Fix email config bool settings crashing on .lower() (value_type=boolean)

Tests: 15 new integration tests for store team member API endpoints.
