CreateSession wrote FormatDateTime(IncHour(Now,24)) = local, but RequireCSRF
and CleanupExpired compare against SQLite datetime('now') = UTC. On negative
UTC offsets the CSRF window fell short of the 24h auth window: between the two,
GETs authed fine but every write got 403 "Invalid CSRF token". Now
IncHour(NowUTC,24) on write + LExpires < NowUTC in Authenticate, so all three
readers are UTC-consistent. Last FormatDateTime(...,Now) in the backend —
closes §2.2 for real. NowUTC + DateUtils already in uses.
