NOW() returns TIMESTAMPTZ. The pattern
(NOW() AT TIME ZONE 'UTC' AT TIME ZONE $userTz)::date
double-converts: first strips the tz designation (keeping UTC wall-clock as
naive TIMESTAMP), then re-interprets that wall-clock as user-local
(pushing UTC into the user-tz's UTC equivalent). For non-UTC users this
gives the WRONG date — e.g. NY user at 9pm sees "today = tomorrow's UTC
date", so opened-today returns 0.
The column-side pattern ((col AT TIME ZONE 'UTC') AT TIME ZONE $userTz)
is correct because the columns are TIMESTAMP without TZ (stored as UTC) —
only the NOW() side was buggy. Replace with (NOW() AT TIME ZONE $userTz)
everywhere.
Affects: dashboard overview/trends, mobile dashboard/engagement/finance.
