feat(heartbeat): default delivery to the configured owner, never groups (#121988)

Unset heartbeat.target now resolves "owner": elected heartbeat notifications deliver to the operator's DM resolved from commands.ownerAllowFrom or the channel allowFrom (first concrete entry; wildcards and channel-scoped wildcards excluded; configured owners exhausted across channels before any channel-local fallback). Delivery requires the channel's own classifier to positively prove a direct destination — every bundled messaging plugin now ships an inferTargetChatType contract — and unproven or group-shaped destinations fail closed to the visible no-route state. The first implicitly-routed delivery carries a one-line self-explanation naming the target: "none" opt-out. Explicit target "last" remains as the follow-the-conversation opt-in. Refines the unreleased #121892 default before it ships; refs #121880.
