flip_stale_sessions flips L1WalkSession.status from 'active' to 'abandoned' for rows where last_step_at is older than 24h. Preserves the row for audit; removes it from the L1 dashboard's 'Resume in progress' widget. Runs hourly via APScheduler with max_instances=1 (Lesson 1). Uses the admin session factory (no RLS context at startup). Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>

"""Hourly cleanup job: flip stale active L1WalkSessions to 'abandoned'.

|
|
Sessions with status='active' and last_step_at older than 24h are considered
|
|
abandoned (L1 closed the browser, customer hung up, etc.). Flipping them
|
|
removes them from the "Resume in progress" widget while preserving the row
|
|
for audit/reporting.

|
|
Run via APScheduler interval job, max_instances=1 (Lesson 1).
