Refactor: Filter staff orders by current date

[devstygian]

Description

Update the staff “View Orders” page to show only today’s orders.
Currently, orders from other dates (e.g., tomorrow) are also displayed, causing mixed data.
Also add a select option to update the food process/status.

Goal

Ensure staff only see relevant (today’s) orders and can easily update order status.

Tasks

• Add date filter (current date only)
• Update query to fetch today’s orders
• Add select option for food process/status
• Update status handling logic
• Test filtering and status update
