fix: restore all 344 unit tests after Wave 8 contributor PRs

- Wrap storage/events/storage_snapshot unit tests in env.as_contract()
  to satisfy Soroban SDK 22's requirement for contract context on storage
  access outside contract invocations
- Fix test_calc_platform_fee_overflow: i128::MAX * 1 does not overflow;
  use fee_bps=2 to trigger genuine ArithmeticOverflow
- Fix three event-detection tests (auto_res, al_tog, al_open) by moving
  env.events().all() checks immediately after the event-emitting call —
  Soroban SDK resets the event buffer between contract invocations, so
  any intermediate getter call clears events before they can be observed
