Returns a list of all project categories configured in the workspace.

**What are Project Categories?**
Categories classify projects by functional area or project type (e.g., Onboarding, Support, Implementation, Website Development). They help organize and filter projects in the workspace. Categories can be configured in workspace settings and support multi-language translations.

**What is returned:**
Each category includes:
- Unique identifier (ID)
- Name and description
- Icon identifier
- Multi-language translations (if configured)

This is a read-only endpoint optimized for common list data retrieval.
