GunterChart v0.215-alpha (build215)

Build215 fixes box opacity edits resetting during refresh, middle-button hover controls and description-field row borders through shared line/box controls. Feedback requests moves to Support without changing its scope. Includes Helper21 with persistent signed version display, repeated restore/update proof renewal and refresh-flicker fixes. Update Helper first, then check for the app update on the chart. Download the Windows ZIP, extract it and open GunterChartUpdater.exe for installation. Restart & update pauses all EAs in that MT5. Restore requires MT5 already closed and explicit confirmation. Older app versions may not support drawing settings created by newer versions. Saved drawing data is retained. Automated checks passed; native post-fix acceptance remains separate. No test trades were placed.
