"""Object pause / seasonal mode (journey N3).
Seasonal equipment (pool, lawn mower, AC) is out of service for months at a
time. Vacation mode is global and archive retires the object entirely —
neither fits "paused until spring". A paused object keeps its tasks visible
(status ``paused``) but freezes schedules and fires nothing; resuming
re-anchors recurring tasks to a fresh cycle, exactly like an object
unarchive.
State lives on the object dict: ``paused_at`` (ISO timestamp marker; set =
paused) and ``paused_until`` (optional ISO date; the coordinator auto-resumes
on the first refresh on/after that day). The resume core is shared between
the ``object/resume`` WS command and the coordinator's auto-resume so the two
paths cannot drift.
Because resume and unarchive make the same "fresh cycle" promise, the
per-task re-anchor itself lives here too (``reanchor_recurring_task``) and is
imported by the object- and task-unarchive handlers — it used to be three
hand-copied blocks that had each forgotten ``due_override``.

The single implementation of the "fresh cycle" promise behind object
unarchive, task unarchive and pause/resume. All three previously inlined

``due_override`` — so a recurring task postponed to a FUTURE date and then
archived/paused came back on that stale postponed date instead of
today + interval, which is precisely what a fresh cycle promises not to do.
Dynamic state lives in the Store when the entry has one; *task_data* is the
static ConfigEntry dict. Pass both where available: the modifiers are
cleared from BOTH because ``MaintenanceStore.merge_task_data`` lets a
static value win when the Store has none, and an IMPORT (websocket/io.py)
can still write ``due_override`` into static entry data after migration has
already run. ``last_performed`` is only written to *task_data* in the
legacy (no-Store) shape.
