- Moved quick-filter panel below toolbar in MgGridBase for improved layout and visual alignment; FilterPanel now renders as a styled band between toolbar and group panel.

- Renamed FilterText to CustomFilterCriteria across grid/data source classes and tests to clarify its role as a DevExpress criteria string.
- Updated documentation (README.md, MGGRID_PARAMETERS.md, GLOSSARY.md, ADR 0004) to reflect filter panel placement, parameter naming, and sizing/layout changes.
- Adjusted CSS for new filter panel layout and visual integration.
- Updated example usages and tests to match new API and layout.
- Introduced `EkaerHistory` entity with status enum and new properties for EKÁER declaration lifecycle tracking.
- Added CRUD methods for `EkaerHistory` in controller interface and SignalR client.
- Implemented `GridEkaerHistory` and `GridEkaerDetail` components for displaying EKÁER records and trade card details.
- Enhanced `TradeCardItemType` with `IId<int>` for grid compatibility.
- Improved AcSignalRDataSource to skip server refresh for tagless/local data sources.
- Updated settings to include .NET 9 runtime install commands.
Moved AcSignalRDataSource and TrackingItemHelpers from AyCode.Services.Server to AyCode.Services (namespace updated). Updated all references, usings, and doc cross-refs to new location. Removed orphan SignalR.Core 1.2.0 package and .Server DLL refs from Blazor/Web.Client/Shared projects; WASM AOT build now works. Introduced AcBinaryDeserExecutor for off-pool streaming deserialization, fixing thread pool starvation (see updated protocol docs). Updated test usings and doc tables. No functional changes to DataSource logic. Decision log entry LLMP-DEC-68 documents the change.
