Refactored the grid filter panel system:
- Renamed "quick-filter panel" to "filter panel" throughout.
- Introduced IMgGridFilterPanelComponent interface for filter panel contract.
- Split MgTagBox (now behavior-free) and new MgGridFilterPanelTagBox for grid filter logic.
- Grid tracks filter panel components, synchronizes criteria, and exposes new filter panel methods.
- Filter panel always rendered (CSS-hidden when off) to prevent invisible filtering.
- Added right-aligned "Clear Filters" button for panel-owned filters.
- Updated docs, parameter tables, and glossary for new terminology and structure.
- Updated usages to new component; legacy grid class implements no-op interface.
- Documented edge cases and updated CSS for new layout.
Extended MgGridBase to support server-roaming of user grid layouts via SignalR, controlled by the new EnableServerLayouts parameter. Updated Save/Load/HasUserLayoutAsync logic and documentation. Added SignalR API methods for grid layout storage. In EKÁER, added TryDepotError to require PartnerDepot before XML generation and enforced gross weight > 0 per line. Updated docs and settings.local.json for new features and automation.
Refactor docs: topic folders, TOON, XCUT, protocol sync
- Migrated all topic documentation into dedicated folders with canonical `README.md`, `ISSUES.md`, and `TODO.md` per topic (e.g., `LOGGING/`, `SIGNALR/`, `BINARY/`, `TOON/`).
- Added comprehensive TOON serializer documentation: design, format, options, attributes, inference, issues, and TODOs.
- Introduced `XCUT` folder for cross-cutting issues and TODOs, with canonical entries and topic cross-references.
- Updated all references and navigation to use new folder-based doc paths; fixed links and clarified doc structure.
- Enhanced AI agent protocol: enforce session skill preloading, `[LOADED_DOCS: ...]` short-name prefix, and mandatory `docs-check` skill for doc/code sync.
- Updated `.csproj` to include all `README.md` files for IDE visibility.
- Improved and clarified SignalR, grid, and project-level documentation.
- Minor code/test tweaks and doc content corrections for consistency.
