Changes:
- ApiTokens.update_last_used/1: Allow Task to access sandbox in tests
- DeviceMonitor.enqueue_check/1: Allow Task to access sandbox in tests
- PollerWorker.enqueue_poll/1: Allow Task to access sandbox in tests
Problem:
When tests spawn async Tasks that access the database, those Tasks
don't have ownership of the database connection in Sandbox mode,
causing DBConnection.ConnectionError warnings.
Solution:
Before accessing the database in a Task, check if we're in test mode
and call Ecto.Adapters.SQL.Sandbox.allow/3 to transfer connection
ownership from the parent process to the Task.
Pattern used:
```elixir
parent = self()
Task.start(fn ->
if Application.get_env(:towerops, :sql_sandbox) do
Ecto.Adapters.SQL.Sandbox.allow(Repo, parent, self())
end
# ... database operations ...
end)
```
All 1041 tests passing. Some harmless disconnection warnings remain
when Tasks complete after tests finish, but these don't affect results.
