The publish goroutine inherited the request context via
context.WithoutCancel. That context carries a request-scoped DB
session returned to the pool when the HTTP handler completes, so
GetProjectByID + access checks in the goroutine raced with session
teardown and intermittently returned empty recipient sets (uids=[]),
silently dropping every SSE board event. Root the detached context in
graceful.ShutdownContext() (global engine, process lifetime).
