Remove the wall-clock approval timeout that auto-rejected pending approvals.
The timeout modeled machine latency, but approvals are human latency
(unbounded); it also created an intent/outcome divergence where a human
approving at the same instant the timeout fired was silently overridden by
the auto-reject. Approvals now block until the operator decides; the
resolved-request dedup still guards against double-submit.
Add ServerMessage.ApprovalResolved and map ApprovalDecisionResolvedEvent to
it in DomainEventMapper so clients are notified when any approval is resolved
(by anyone) — letting a second connected client clear its prompt. This is the
event-sourced replacement for the removed timeout notification path.
Drop the now-dead ApprovalConfig (timeout_ms) and its loader/test/sample-config
references. ApprovalStatus.TIMED_OUT is retained for replay of historical events.
