After migration to async db operations, the throttle decorator also
needs to support async. Since the decorator is only used for async funcs
now, we can just switch it to async instead of supporting sync and async
at the same time.

* perf(channels): batch user lookup in model_response_handler thread history
The thread-history builder in model_response_handler called
Users.get_user_by_id once per thread message (deduped via an intra-loop
dict), producing N individual SELECTs for a thread of N unique authors.
Replace with a single Users.get_users_by_user_ids call that returns all
authors in one WHERE id IN (...) query, matching the batch pattern
already used elsewhere in this file (lines 739, 804, 1320).
Behavior is preserved: deleted users still resolve to None and fall
through to the existing 'Unknown' fallback via .get().
* refac(channels): rename loop vars to full words per review
Address reviewer feedback to use descriptive names `message` and `user`
instead of single-letter `m` and `u` in the batch user-lookup
comprehensions.

After set_access_grants, the handler was reloading the same knowledge
record via get_knowledge_by_id, which triggers an extra SELECT plus a
nested fetch of access grants. set_access_grants already returns the
newly-written grants and the local knowledge object is otherwise
unchanged, so update it in place and reuse it for the response.
