strip: remove pattern/surge/chat alert monitoring + unused commands

- delete services/{patternChecker,patternStore,surgeChecker,chatAlertChecker,staffNotifications,staffChannel,notificationRegistry,notificationEnabled,staffPresence}.js
- remove /notification, /staffnotification, /tag, /priority
- /escalate: drop action param, always unclaim
- purge PATTERN_*, SURGE_*, CHAT_ALERT_*, STAFF_* env vars from config + .env.example
- drop StaffNotification model
- ~2500 LOC removed
- settings-site /internal/notifications/* endpoints gone (UI will 404 until trimmed)
