Enhance the service item management page with proper search, filter, and bulk update capabilities, as well as the ability to clone service items to rooms.

Problem:
For a single location, we have uploaded 59 pages of catering/service items. Managing these items in the current interface is extremely difficult and time-consuming because:
• There is no search function to find specific items
• There is no filtering (e.g., by category, location, or status)
• There is no bulk update option — changes must be made item by item
• There is no cloning functionality — when a new room is added, all service items must be assigned manually, one by one

Adding 50+ items to a new room by hand is frustrating, error-prone, and not scalable.
Proposed Solution:
1. Search
• Allow administrators to search service items by name, category, or keyword
2. Filter
• Provide filter options (e.g., by category, location, room, status, price range)
• Enable quick navigation through large item catalogues
3. Bulk Update
• Allow mass editing of service items (e.g., update prices, descriptions, or availability for multiple items at once)
4. Clone Service Items to Rooms
• Ability to clone/copy an entire set of service items from one room to another
• Select a source room and apply its service item configuration to one or multiple target rooms
• Eliminates the need to manually add 50+ items per new room

Business Impact
• 59 pages of service items for just one location — current interface is unmanageable
• Manual room setup is extremely time-consuming and frustrating for administrators
• Risk of errors and inconsistencies when adding items one by one
• Proper search, filter, and clone functionality would drastically reduce admin effort and improve scalability
• Essential as more locations and rooms are onboarded
