fix: enable concurrent status computation to prevent multi-minute delays

Set StatusComputeWorkers=8 on DefaultStatusWatcher for Wait,
WaitWithJobs, and WatchUntilReady. This opts in to the async status
computation added in fluxcd/cli-utils#20, preventing the informer
notification pipeline from being blocked by slow API calls when many
resources are updated simultaneously.

Without this, status computation for resources like Deployments (which
require additional LIST ReplicaSets/Pods calls) runs serially inside
the informer, causing growing delays of 1-3+ minutes when upgrading
many resources at once (e.g., ~20 Deployments via Helm).
