what a new run launched now would send

Simplify signature of `DatabaseOperations.execute_sql_flush()`
Description
	
The current signature is:
def execute_sql_flush(self, using, sql_list):
The using argument can be dropped and inferred by the calling instance: self.connection.alias.
def execute_sql_flush(self, sql_list):
Some internal ises of this method are already doing:
connection.ops.execute_sql_flush(connection.alias, sql_flush)

Work only inside this repository checkout. Make the code change the task
describes, keeping the diff focused — no drive-by refactors.

When you are done, leave your changes committed or in the working tree;
they are collected automatically.

Stay on this snapshot checkout (`task/ycb_django_pr12741`). Never checkout, pull, or rebase onto `main`. That branch is a README-only orphan.
Stay on this HEAD. Do not fetch another default branch. Push only on the Cursor-created `crazy-cursor/…` side branch from this HEAD.

Some past runs of this task were launched with a different prompt (the prompt template changed since, or those runs predate this benchmark's stored prompt). Each run persists the exact prompt it sent at launch — that per-launch record is the audit trail; this page shows only the current one.
