BE-3 observability: expose the worker's Prometheus metrics on :6060/metrics
(apns/fcm/asynq histograms + a new cache_ops_total counter were recorded all
along but never scraped — which is why those dashboard panels read empty); add
the worker containerPort, the vmagent worker scrape job, and two additive
NetworkPolicies. Instrument cache Get/Set hit/miss.
BE-2 retention: three periodic Asynq cleanup crons mirroring the reminder-log
cleanup — notifications (90d), webhook dedup log (180d), audit_log (365d).
BE-1 GDPR data export: POST /api/auth/export/ enqueues a low-priority Asynq job
that gathers all of the user's data (owned residences + their tasks/contractors/
documents/share-codes, plus profile/notifications/prefs/push-tokens/subscription/
audit log), zips one JSON file per category, and emails it as an attachment.
