Migrate remaining edge functions to wrapper

Refactor process-expired-bans, detect-location, detect-anomalies, rate-limit-metrics, and collect-metrics to use createEdgeFunction wrapper with standardized error handling, tracing, and reduced boilerplate. Update signatures to receive { supabase, span, requestId } (and user where applicable), replace manual logging with span events, remove per-function boilerplate, and ensure consistent wrapper configuration (cors, auth, rate limits, and tracing).
