Lucas BergerandClaude Opus 4.8 d168da71cf fix(18): WR-01 treat empty/blank TZ as unset in household timezone fallback
The D-06 fallback used row?.value ?? process.env.TZ ?? Intl..., but ??
only short-circuits on null/undefined. A set-but-empty TZ ('' or '   ')
leaked through and yielded an invalid IANA zone that throws inside
Intl.DateTimeFormat({ timeZone }) downstream, silently dropping the
all-day reminder. Extract resolveHouseholdTimezone() which trims and
treats empty/whitespace candidate values (stored value and TZ) as
absent so they fall through to the Intl resolved zone. Adds RED->GREEN
unit tests for empty and whitespace-only TZ.

Lucas Berger db0077c3c3 test(18-01): add failing tests for household timezone accessor + IANA validator
- RED gate: tests for getHouseholdTimezone fallback chain (stored → TZ env → Intl)
- Tests for null row value falling through to TZ env branch
- Tests for isValidIanaTimezone (UTC, Etc/UTC, America/Chicago, Europe/London pass; garbage fails)
- Mock Drizzle select chain follows requireAdmin.test.ts pattern
- Saves/restores process.env.TZ in beforeEach/afterEach to prevent env state leaks
