improvement(testing): consolidate @sim/db mocks into one table-aware chain mock

- back databaseMock and dbChainMock with the SAME db instance so a module
  bound to either export hits identical chain fns — rival-mock divergence
  between the two @sim/testing db mocks is structurally impossible now
- add queueTableRows(table, rows): FIFO per-table select routing keyed by
  schema-mock table identity, consumed at where() materialization and
  resolved by every downstream terminal (limit/orderBy/groupBy/for/joins)
- delete createMockDb (duplicate chain implementation, no external users)
- migrate the five suites that hand-rolled table routing + databaseMock
  delegation (billing plan/usage/usage-log, admin dashboard-organizations,
  workspaces/utils) onto queueTableRows; net -295 lines
- add a contract test for the mock itself and a test script to
  @sim/testing so its tests actually run under turbo
