* fix(whatsapp): add idempotent message sending to prevent duplicates on timeout retry
When sending media messages via Baileys, Net::ReadTimeout causes Sidekiq to
retry the job, potentially sending the same message multiple times. This adds
a chatwootMessageId parameter to the Baileys API request, enabling server-side
deduplication via Redis. Also increases HTTP timeout to 120s and channel lock
to 130s to reduce false timeouts.

* fix: address review feedback
- Use error.class.name assertions for parallel/reloading safety
- Assert reconnect endpoint was not called on 409 (stronger assertion)
* fix: address review feedback (round 2)
- Only release channel lock in ensure if it was actually acquired (prevents
clearing another worker's lock on timeout)
- Assert chatwootMessageId in reproduction spec body matcher
