Updated the Sale Return filters to use the company timezone for all preset date filters (Today, This Week, This Month, etc.), passed the required `timeFilter`, `YYYY-MM-DD`, and `timezone` parameters in the API, and removed UTC hardcoding from the backend and export functionality to ensure consistent date filtering.
Fixed the timezone handling in Product Quotations so that filtering is based on the company timezone and made the filtering behavior consistent across Products, Sales, and Product Quotations.
Added validation to the Product Purchase Date field to prevent selecting future dates and fixed the date picker so the maximum selectable date is always limited to the current date.
