fix: fire a one-time schedule on the exact chosen date and time (#1497)

Simple "Once" schedules compiled to a 5-field cron, which has no year field, so
the scheduler computed the next run as the next annual occurrence. A date chosen
for a later year ran a year early, and a time already elapsed today ran a year
late, contradicting the UI promise that the task fires on the chosen date.

One-time schedules now send the chosen absolute timestamp (run_at) and the
backend pins next_run_at to it instead of the cron-derived next run, so the run
fires on the exact selected instant including the year. The Simple-mode
validation now compares the full chosen instant against the current time, so a
time earlier today is rejected as past rather than silently deferred a year.
run_at is validated as a finite, future epoch-millisecond timestamp on create
and update. The enable/disable toggle preserves a one-shot's pinned next_run_at
(its yearless cron cannot reconstruct the chosen year), so re-enabling restores
the exact instant. Recurring shapes and Advanced mode are unchanged (cron stays
authoritative).
