- Return 302 to /static/favicon.png instead of streaming the same PNG per
model id so browsers can cache one asset for default avatars.
- Validate stored /static/ paths with decode, normpath, and /static
prefix checks; invalid paths fall back to favicon.
Made-with: Cursor
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.
