Made the table wider, used icons to compact space

[snipe]

Made the table wider for more info and readability

[what-the-diff]

• Changed the column widths of the table to be more responsive.
• Added icons for each row in order to make it easier to see what type of item is being counted (assets, accessories, licenses and consumables).
• Removed some unnecessary CSS classes from HTML elements that were not used by any stylesheets or JavaScript files within Snipe-IT's codebase. This was done as part of a larger effort towards removing unused/unnecessary code throughout this project's repository which can help reduce complexity and improve maintainability going forward into future releases! :)
