When a monitor task's final account hits human verification or an
authorization failure, cancel the remaining queued desktop/monitoring
tasks for the whole platform instead of only the same account. Follow-up
tasks are now marked skipped/aborted (not failed) with a
platform_human_verification / platform_authorization_unavailable reason
and a user-facing cancellation message, and emit task_canceled lifecycle
events for monitor kinds.

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.
