FIX / Fix MySQL when calculating amounts

[Mary-Clb]

• I have performed a self-review of my code.
• I have added tests (when available) that prove my fix is effective or that my feature works.
• I have updated the CHANGELOG with a short functional description of the fix or new feature.
• This change requires a documentation update.

Description

• It fixes !42462
• The total amount of orders was no longer being calculated due to a SQL syntax error in the getAllPrices() function query. The query builder was incorrectly adding backticks around SQL expressions, resulting in the following MySQL error: SQL Error "1054": Unknown column 'SUM(price_ati)' in 'SELECT'
  The query has been corrected by wrapping the SELECT expressions in QueryExpression objects, which tells the query builder to treat them as raw SQL expressions rather than column names.
