Improve toolbar controls and async UX in stock taking

- Added EnableNew and EnableEdit parameters to MgGridToolbarTemplate for finer control of toolbar button states.
- Disabled "New", "Edit", and "Delete" actions in history and item grids by passing explicit parameters.
- Introduced DxLoadingPanel in StockTakingTemplate for better async feedback.
- Disabled "New" and "Close" buttons during async operations to prevent duplicates.
- Enhanced combo boxes with search/filter and usability features.
- Updated new/close stock taking logic to show loading, handle errors, and prevent duplicate actions.
- Set focus to item combo box after saving a StockTakingItemPallet.
- Removed global loading panel from StockTaking.razor; loading is now handled locally.
- Performed minor code cleanups and removed obsolete code.
