PoS Category - Complete Name

This module extends the Point of Sale category model (pos.category) by adding a computed field called 'Complete Name'. The field displays the full hierarchical path of a category, combining the parent category's complete name with the current category's name, separated by a slash. For example, if you have a parent category 'Drinks' and a child category 'Soft Drinks', the complete name will be 'Drinks / Soft Drinks'.

The field is automatically calculated and stored in the database, so it updates whenever the category name or its parent's complete name changes. The module also sets the category's display name to use this complete name, which means that in many places where categories are shown (like dropdowns or lists), you will see the full path instead of just the category name.

This makes it much easier to search for and distinguish between categories that have the same name but different parents. For instance, if you have 'Food / Snacks' and 'Drinks / Snacks', searching for 'Snacks' will show both with their full paths.

The module does not add any new menus or screens; it simply enhances the existing Point of Sale category configuration. It relies on the standard Point of Sale module and does not introduce any new business rules or restrictions beyond the automatic computation of the complete name.
