Publish each lookup table together with its partitions and temporary path. Close superseded unconsumed tables to avoid leaking their cache state. Signed-off-by: QuakeWang <wangfuzheng0814@foxmail.com>

Purpose
Async partition refresh previously published the lookup table separately from its partitions and temporary path. A completed table could therefore be paired with state from a newer refresh generation.
Publish the lookup table, partitions, and path as one atomic refresh result, and close superseded unconsumed tables.
