EKÁER grid: status enum fix, batch create, UI/UX, DB guard

- Fixed EkaerHistory status persistence (int+enum wrapper for linq2db)
- Added batch EKÁER record creation (toolbar date picker, SignalR, UI)
- Enhanced GridEkaerHistory: status, error, XML copy, manual edit
- Improved column display format handling in MgGridInfoPanel
- Updated SignalR binary protocol streaming strategy doc
- Added DB guard PowerShell hook: blocks non-_DEV DB shell access
- New styles for EKÁER toolbar date picker
