copy: rego throughout the guests page, visitor page, tour, guides and emails

The second pass of the settled vocabulary. Every user-facing "car",
"vehicle" or bare "plate" that means the rego on the permit now says
rego: the guests page and its confirms, the visitor's own page, the
schedule's remaining tooltips and errors, the Regos, Settings, Activity
and onboarding pages, the landing page, the features tour, the FAQ and
guides, and the failure, drift, expiry, re-link and driver emails.

"Number plate" stays wherever it already appeared, and "car" stays where
it means the physical vehicle: the car parked at the kerb, the car that
is fined, the metal plate a rego is checked against, the paper permit
that moved between cars.

The overnight option no longer says every activation ends at the end of
the day, which was wrong: when a window ends the roster takes over, and
with nothing scheduled the rego stays on the permit until the next
change. The guests intro says the rego a visitor puts on is their own,
chosen from the household's saved list.

Page and email goldens regenerated; the diff is the intended lines.
