- Switch opened_today / resolved_today / yesterday / 7d-avg buckets from
CURRENT_DATE to ((value AT TIME ZONE 'UTC') AT TIME ZONE $1)::date.
- Both routes destructure session from requireAuth() and resolve tz via
getUserTimezone(); tz parameterized as $1 (no SQL interpolation).
- Preserved unchanged: due_date_time < NOW() (rolling SLA, tz-independent),
the INTERVAL '24h/5min/1h' rolling-window queries (failed backups,
stalled workflows, analyzer/RMM 1h fail counts, backup-success 24h).
- Added a code comment above the 24h failed-backups query explaining why
it stays UTC-NOW relative.
