Transaction created_at and completed_at showed identical timestamps
because webhook handlers created transactions with is_completed=True
in a single step. Now all 10 payment providers pass payment.created_at
to the transaction so created_at reflects when the user initiated
the payment, not when the webhook processed it.
Also: remove duplicate datetime import in inline.py, upgrade button
stats DB error logging from debug to warning, add index on
button_click_logs.button_type for analytics queries.
