feat(scheduler): dispatch event on job failure, notify admins via notifications module

Add ?ModuleEventDispatcher to SchedulerRunService (fail-open, nullable).
Dispatch scheduler.job_failed event when a job fails with payload:
job_id, job_key, label, error_code, error_message, trigger_type.

New SchedulerJobFailedNotificationListener in notifications module
creates in-app admin notifications for users with JOBS_MANAGE
permission, scoped per tenant, with 30-min dedup per job_key.

Also fixes audit module manifest: system_audit_purge job_key was
mismatched (audit_system_purge vs system_audit_purge in DB).
