The middleware's per-request user lookup (ghost-session guard) fetched
the full row and discarded it, then built the context stub without a
timezone — so every server-side conversion via the context user fell
back to UTC no matter what the handlers did. The stub now carries
Timezone from that same lookup (fetchLiveUser).
Live-verified: progress page renders 02:03 PM for a 14:03 New York
instant; an analytics session at 02:00 UTC buckets to 10-12 (10pm NY
the previous day) instead of 10-13.
