📝 WalkthroughWalkthroughAdds HTTP timing middleware for publish requests and correlates its records with handler timing through a shared ID. Adds timing for worker dispatch and named publish phases, wires the middleware into the application, and adds tests for timing records and request outcomes. ChangesPublish timing

In `@reflexio/server/publish_timing.py`:
- Around line 602-609: Update the authenticated organization dependency to
record the identified organization ID on the active `_HttpScope` as soon as the
dependency returns, before billing rejection or handler startup can occur.
Preserve `"unknown"` when authentication fails before identifying an
organization, and document that only those requests use the shared unknown
throttle bucket.

Summary
Publish handler timings exclude authentication, billing dependencies, and response completion, leaving slow HTTP requests difficult to explain. Add a separate HTTP timing event correlated with the existing handler event, preserving the handler's acknowledgement semantics.
Changes
timing_id; identify extraction waits and unfinished workers explicitly.Test Plan
No request/response schema, new environment variable, or production topology changes. This adds diagnostic evidence; it does not claim the 5,000 ms production target is met.
