OTC Bot Entry Watcher V16 — No Fake Prices

Fix:
- No synthetic/fake exit price.
- If Pocket result is visible but exact exit price is not visible, sends:
  resultOnly=true
  entryPrice = real entry if available or 0
  exitPrice = 0
- Server V12 must be installed to accept result-only Pocket outcomes.

Expected server log:
POCKET RESULT ONLY SAVED V12: ... note=no fake prices

Install:
- Remove old extension.
- Load unpacked folder pocket-click-watcher-v18-clean-domain-permissions.
- Server URL: https://rsignal.org
- Close Pocket tab and open it again.
