refactor: eliminate code duplication in forceQdrantSync endpoint

Replaced four identical for loops (one per content type) with a single
loop that iterates over an array of content types. This reduces code
from ~48 lines to ~20 lines while maintaining identical functionality.

Benefits:
- Easier to maintain and modify
- Less prone to copy-paste errors
- More readable and cleaner code structure
