feat(system_users): implement user status enum and migrate from boolean flag

- Add UserStatus enum with states: ACTIVE, INACTIVE, SUSPENDED, LOCKED, PENDING_ACTIVATION
- Replace is_active boolean field with status enum field in SystemUserModel
- Update CreateUserRequest and UpdateUserRequest schemas to use status field
- Update UserInfoResponse schema to reflect status field instead of is_active
- Migrate EmployeeService to use UserStatus.ACTIVE when creating system users
- Migrate MerchantService to use UserStatus.ACTIVE and remove duplicate status field
- Update system_users router documentation to reference status_filter parameter
- Rename is_active filter parameter to status_filter in list_users endpoint
- Add migration utility scripts for status field migration
- Provides better semantic clarity and extensibility for user account states
