Subject: [PATCH] fix(model): invalidate channel cache after status update

UpdateChannelStatusById() updates the database but does not refresh
the in-memory channel cache (group2model2channels). When
MemoryCacheEnabled is true, the stale cache means disabled channels
continue to receive traffic until the next SyncChannelCache cycle
(default 600 seconds).

Call InitChannelCache() after a successful status update to ensure
the cache is immediately consistent with the database.
