d362858f46 fix(notification): ack notifications can join the caller's transaction (#603)
The release engine's bell notification for a just-originated proposal
inserted through a fresh session while the proposal task sat uncommitted
in the engine's own transaction — the related_task_id FK rejected the
row and the ping was silently lost (caught live in the postgres log; the
DB-free Telegram DM still went out). send_ack_notification now accepts
db_session, forwarded to _create_notification so the insert joins the
caller's transaction, and the release engine passes its session. The
other five callers pass no task_id or reference committed tasks.

"""send_ack_notification must be able to join the caller's transaction.
The origination engines notify about a task their OWN open transaction just
created; a fresh session cannot see that uncommitted row, so the
notifications.related_task_id FK rejects the insert and the bell
notification is silently lost (the 0.26.0 release-proposal case, caught in
the live postgres log). Real-Postgres coverage for both directions.
