fix(gateway): only session-discover channel targets for connected platforms (#60574)

Session-based channel discovery resurrected historical origins for
platforms with no connected adapter, exposing stale send_message
targets that can no longer deliver. Gate both the enum loop and the
plugin-registry loop on the live adapter set.

Surgical reapply of the channel-directory portion of PR #25959 (branch
was 6.5k commits stale; the text-batching delay changes bundled there
were dropped - separate concern, defaults have since been retuned on
main).
