  Remove @Cacheable from getFirstBillingDate — LocalDateTime + Redis incompatibility
  
  The redisOneDayCacheManager (CacheConfig.java:109-116) is configured with
  enableDefaultTyping(NON_FINAL, JsonTypeInfo.As.PROPERTY). That embeds type info
  as a JSON object property, which is only valid for objects ({}) — not arrays.
  JavaTimeModule serializes LocalDateTime as an array ([y,m,d,h,m,s]), so the
  write drops type metadata and reads fail with MismatchedInputException
  ('need JSON String that contains type id').
  
  The underlying NamedQuery (Order.selectFirstBillingByRetailer) uses MIN() on
  the idx_order_customer_billing composite index — EXPLAIN reports 'Select tables
  optimized away'. Per-call latency is microseconds even uncached, so Redis
  caching was optimization rather than requirement. Simpler to drop the annotation
  than reconfigure the shared cache manager.
