Paul Trowbridge 13e49c14b6 Offer negative clone offsets, and validate the interval before using it
Shifting backwards already worked -- the offset is added as a Postgres
interval, and '-90 days' is a perfectly good one -- but the suggestions only
listed forward shifts, so nothing said so. Pulling a plan back a quarter is
a normal thing to want.

A day-level shift is also the case that most needs the dim_period
derivation: 15 Mar 2027 less 90 days is 15 Dec 2026, which crosses from
2027/10 - Mar into 2027/07 - Dec. Copying the period columns across would
have labelled it March.

The offset is interpolated into the statement, so a typo surfaced as a
Postgres parse error from the middle of a CTE. It is parsed on its own
first, where the failure is cheap and can name the field.
