chore(backend): remove unused memories-created quota/limit

The "memories created this month" limit was display-only — nothing
enforced it. Drops PlanLimits.memories_created, the memories_created_used/
_limit fields from UserSubscriptionResponse, and the
BASIC_TIER_MEMORIES_CREATED_LIMIT_PER_MONTH env var from charts. The
memories_created usage metric (analytics) is untouched.
