fix(kanban): route active named profile through the active adapter map

A gateway running under a named active profile (e.g. `hermes -p main gateway`)
stamps kanban auto-subscriptions with notifier_profile=main, but
_authorization_adapter() treated any name other than the literal "default"
as a multiplex secondary and consulted only _profile_adapters — empty on
standalone gateway-per-profile deployments. The helper failed closed, the
notifier rewound the claim, and the notification was silently retried
forever (#71340).

Recognize the gateway's own active profile name as primary so its stamped
subscriptions resolve via self.adapters; genuinely secondary profiles keep
the fail-closed lookup.

Salvaged from PR #62380 (the unrelated blocked-reason truncation change is
intentionally not taken).
