fix: remove HL-delisted coins from scanner (BNT/CATI/CYBER/ILV/LISTA/OGN/STG) + PIXEL

Root cause: HL WS uses allMids (all coins), BG WS subscribes per-coin.
Delisted coins had stale HL prices showing huge fake spreads (~200%).
Monitor tried entry → BG buy succeeds, HL sell fails (Trading is halted)
→ orphan position on BG accumulated across restarts.

Fix:
- Set HL="" for BNT, CATI, CYBER, ILV, LISTA, OGN, STG, PIXEL
- Add guard in ScanBGHL to skip coins where BG or HL is empty
- Same guard in SpreadWindowTracker.Tick
