v5.2: hold weekend block all Friday + close by Thu midnight ET

CheckWeekendProtection previously returned true after the one-shot
weekend close, so the EA resumed placing new grids for the rest of
Friday. Now it stays blocked until the next trading day and keeps
sweeping stray positions/pendings while blocked.

All 17 presets: InpWeekendCloseHour 17 -> 7 (server UTC+3), closing
everything at Friday 07:00 server = Thursday midnight ET, per the
no-weekend-carry policy.
