feat(iios): idempotency ledger on outbound egress (409 on key reuse) (P9)

Browse Source 
OutboundService.send is now opt-in idempotent: an explicit idempotencyKey routes
the send through IdempotencyService.run (Slice 6), so reusing a key with a
different target/payload returns a 409 conflict and a same-key/same-request retry
replays the cached command. The inner findUnique early-return stays as a backstop
so a FAILED-then-retried send never collides on the command's unique key. Keyless
sends keep the old behavior (no ledger row).
