v5.8: self-heal gridPlaced from real broker state at OnInit

Fixes the duplicate-grid bug found 2026-08-11: gridPlaced (and the
rest of SaveGridState's GlobalVariable-backed state) never reaches
disk in this environment -- confirmed no .gvr file exists anywhere
under the MT5 data dir. Every full container restart mid-cycle wiped
it back to false while a grid was still resting live on the broker,
and OnTick would place a brand new duplicate grid on top of the old,
uncancelled one. Found 189 stacked pending orders account-wide before
cleanup (CancelAllPendingNow.mq5), one symbol alone had 29 spanning
24+ hours of normal cycles -- this has likely been happening on every
watchdog restart for weeks, not just from that day's testing.

Adds HasLiveGridPresence(): checks actual OrdersTotal()/PositionsTotal()
for this symbol+magic. At OnInit, if gridPlaced reads false but real
orders or positions already exist, trust reality over the flag and
recover gridPlaced=true -- so a restart mid-cycle can no longer cause
a duplicate placement, regardless of whether GlobalVariable persistence
ever gets fixed underneath. Deployed and recompiled live (all 14 EAs
confirmed reinitialized as v5.8); not yet validated against a live
container-restart cycle given the risk of disrupting the account
further right after cleanup -- logic mirrors the existing broker-state
query pattern already used in OnTick's monitor branch.
