feat(monitoring): fail same-client queued tasks on desktop authorization failure

When a desktop monitoring task fails with a non-retryable authorization failure
(login expired, challenge required, risk control), all pending same-client/same-platform
tasks for the same business day are immediately bulk-failed as non-retryable, avoiding
wasted execution attempts. Adds preflight authorization checks before task execution,
enriches failure payloads with disposition metadata (code, category, retryable flags),
and triggers account health reports on auth state degradation.
