v5.3: Monday morning stand-down until 07:00 server

Monday's pivots and ATR are built from Friday's session and the first
server hours are the thin Sunday-evening ET market — historically the
only losing weekday (-$121 across 204 trades vs all other days
positive). New CheckMondayStandDown() blocks new grids on Monday
before InpMondayStartHour (default 7 = midnight ET), and because it
sits above the daily pivot recalc, Monday's pivots/ATR are sampled at
the resume hour instead of the rollover. All 17 presets set
InpMondayStartHour=7. Trading week is now Mon 00:00 ET -> Fri 00:00 ET.
