Decide quest-log overdue from the panel's own local clock

The kids' Quest Log rendered OVERDUE from the API's per-instance
`overdue` flag, which is computed on whatever wall clock the API
resolves for the household. When that clock is UTC (HA `time_zone`
UTC, a pre-0.9.6 API/integration, or a stored zone adopted over),
an 8:15 AM quest reads OVERDUE at 7:15 AM America/New_York.

The card now marks an open quest overdue when its `due_time` wall
time has arrived on the panel browser's local clock (`_now`, a
reactive state ticking every 60 s; `>=` so it flips on the due
minute). With no `due_time` a quest is never overdue, matching the
API's rule. The API's `overdue` field is unchanged for admin and
automation consumers; the card simply no longer reads it.

The jsdom quest-log harness can now pin the clock (`now`) and fire
the card's own clock tick at later instants (`advance_to`), and the
Python helper sets the node process `TZ`.
