Make table headers draggable and save column order

[techmore]

Table headers (columns) in the asset/results table should be draggable to allow users to reorder columns according to their preferences. The custom column order should be saved and persisted across sessions.

Current state:

• Table columns are fixed in order
• No ability to reorder columns
• Column preferences not saved

Desired functionality:

• Implement drag-and-drop for table headers
• Allow reordering of columns (IP, Hostname, MAC, Vendor, etc.)
• Save column order in localStorage or user preferences
• Restore saved column order on page load
• Maintain functionality when columns are reordered

Implementation details:

• Use a JavaScript library like SortableJS or native HTML5 drag-and-drop API
• Store column order in localStorage
• Update table rendering to respect saved order
• Ensure sorting and filtering still work with reordered columns

Location: Modify table rendering in and related JavaScript for the results table.

This enhancement will improve user experience by allowing customization of the table layout.
