[12.0][FIX] queue_job: don't enqueue dependent jobs after a retryable postpone (closed cursor)

[MiquelRForgeFlow]

Problem

Graph jobs that hit a Postgres serialization/concurrency error crash the /queue_job/runjob request with:

psycopg2.OperationalError: Unable to use a closed cursor.

Traceback tail:

controllers/main.py, in _enqueue_dependent_jobs -> job.enqueue_waiting()
job.py, in enqueue_waiting -> self.env.cr.execute(...)
OperationalError: Unable to use a closed cursor.

Root cause

In RunJobController.runjob, the except RetryableJobError handler calls the local retry_postpone(), which does:

job.env.clear()
with odoo.registry(job.env.cr.dbname).cursor() as new_cr:
    job.env = job.env(cr=new_cr)
    ...
    new_cr.commit()
# new_cr is closed here, but job.env.cr still points at it

The handler ended with env.cr.rollback() but no return, so control fell through to self._enqueue_dependent_jobs(env, job) ->
job.enqueue_waiting(), which runs self.env.cr.execute(...) on the closed cursor. This only triggers for jobs in a dependency graph that hit a retryable error, which is why it's intermittent.

Fix

Return right after the rollback in the RetryableJobError branch. A postponed job isn't done, so it must not release its dependents — and this avoids using the closed cursor. This matches upstream OCA queue_job behaviour in 14.0/15.0/16.0.
