Added new icons for quick search by product and search by specific words

Added new icons for quick search by product and search by certain words (with data filtering by cost, availability).

Now the search can work not only by keyword, but also with a price limit (from and to).

You can also filter accounts by quantity in stock (from a certain quantity).

Added data filtering by the following properties:

- First, dears
- Cheap ones first
- Sorting from A-Z (by product name)
- Sort from Z-A (by product name)

It is also possible to view products with zero positions.
