• 916be25 (from 8cf0f7d) fix(site-backup): Repair a crashed global search table on the site's bench

Conflicts resolved

• press/press/doctype/site_backup/test_site_backup.py, import block: on develop the PR turned the existing alert_if_backup_success_rate_is_low import into a multi-line import that also brings in is_global_search_crashed. master doesn't have alert_if_backup_success_rate_is_low, so this backport imports only is_global_search_crashed.

That import line is the only difference from the original PR's diff (test file is +45/-0 here vs +48/-1 on develop). press/agent.py, press/fixtures/agent_job_type.json and site_backup.py applied cleanly and match line for line.
