Account incineration could leave orphaned records due to missing cascade
declarations and async jobs failing when the account was already gone.
Cascade fixes:
- Add Account::Searchable concern to clean up Search::Query (delete_all)
and Search::Record (destroy_all, respects SQLite FTS dependent: :destroy)
- Add before_destroy in Account::Storage to delete storage entries
- Suppress storage entry recording during incineration so attachment
purge callbacks don't create entries or enqueue materialize jobs
- Guard Access#clean_inaccessible_data_later with unless user.destroyed?
to avoid enqueuing pointless jobs during user cascade
Job tenancy:
- Extract AccountTenanted concern from the global ActiveJob initializer
into ApplicationJob (include) with targeted prepends for
ActionMailer::MailDeliveryJob and Turbo broadcast jobs
- Defer account resolution from deserialize to perform so that missing
accounts raise DeserializationError inside the execution path where
discard_on can handle it
Tests:
- Comprehensive incineration test covering 35 model types with
before/after assertions and full enqueued job processing
- Mailer deliver_later test verifying account context survives job
serialization for multi-account users
- Turbo broadcast test verifying account-scoped URLs in rendered partials
