Definition of `categories` Array is Duplicated and Loosely Defined

[tim-rohrer]

Problems

1. The categories array, which defines filter groups and their options, is currently duplicated in three different places within the codebase. This leads to:

   • Increased maintenance effort (changes must be made in multiple locations)
   • Higher risk of inconsistencies and bugs
   • Reduced code clarity and reusability

2. Further, each type definition includes the primitive string[]. This is too broad, and may lead to unexpected assignments.

Proposed Solution

• Refactor the codebase to define the categories array in a single, dedicated file (e.g., src/components/filters/filterCategories.ts) without including primitives.
• Import and use this shared definition wherever filter categories are needed.

Benefits

• Easier maintenance and updates
• Consistent filter group definitions across the app
• Improved code readability and organization

Action:
Refactor the code to centralize the categories array and to remove duplicates and primitives.
