Improvement of the catalog for the website

For the catalog website, improvements need to be made: (the work can be divided into stages or taken by qualification part)

1. In the admin panel, the ability to upload SQL files for updating prices (in the archive is price_balluff_2026_for_site.sql). (currently they are uploaded by the programmer, it needs to be for the future so that the admin can upload) A sample file is attached

2. Generation of descriptions using GPT (API is connected), it is necessary to refine descriptions for certain categories of products, and where there is already a description, do not touch it, only where there is

*A product without a description has a placeholder text: - is an industrial component of Balluff in the category "Mechanical limit switches". A detailed description will be added soon.

EXAMPLE

- A product with a placeholder https://balluff-ua.com/bns-813-d04-r12-100-22-04-bns010r

- A product with a description https://balluff-ua.com/bes-m12mi-psc40b-bv03-bes0001

Start with descriptions of Inductive sensors - https://balluff-ua.com/product/inductive (everything in Ukrainian)

!!! First, approve the prompt for GPT in the form of Brief about the product, Characteristics, Application

3. Images in sections and subsections (if there are no photos for the category, the product photo is used).

Specify a general photo for the corresponding category for products in them, for example, the product photo https://balluff-ua.com/bns-819-100-r-11-bns006e, and when you go to the category, there are placeholders https://balluff-ua.com/product/mechanic. It is necessary to prioritize; if a photo is uploaded manually, it takes priority.

-------------------------------------

As a separate task

4. Speeding up the website, (the preloader loads) we need to understand why it is needed there, it would be wonderful if we could get rid of it and the website would load faster.
