Rooms: UI for Managing Hotel Rooms

[cliffdoyle]

Build the user interface for staff to manage all rooms in the hotel. This UI will consume the API from issue .

Frontend Tasks:

• Create a RoomsPage.jsx under a new /settings/rooms route.
• Fetch and display all rooms from GET /api/rooms in a table.
• Create a "New Room" button that opens a modal with a form to add a room (POST /api/rooms).
• Add "Edit" and "Delete" buttons to each row in the table, which trigger the respective PUT and DELETE API calls.
• Ensure the UI updates automatically after a room is added, edited, or deleted.
