test(users): isolate count unit test from Organization model (deterministic CI)

Add repository-level mocks for organizations.repository.js and
organizations.membership.repository.js so mongoose.model('Organization')
is never evaluated at module-link time with --maxWorkers=2.

Service-level mocks intercept call paths but ESM static imports on the
real service files are still resolved by the V8 VM module linker in CI,
causing MissingSchemaError when the Organization schema hasn't been
registered yet in that worker's context.
