Sync date filter UI with filter criteria in BandGridBase

Browse Source 
Added logic to synchronize the date filter UI with the current
filter criteria by updating _filterFrom and _filterTo based on
the CriteriaOperator. Introduced SyncDateFilterFromContext and
ParseDateOperand helpers to extract and apply "from" and "to"
date values, ensuring UI and filter state remain consistent.
