Pull Request Overview

Updates the home page to dynamically display isolate counts for all special collections instead of hardcoding specific bacteremia and nares counts. The change makes the system more flexible by automatically showing counts for any special collection type present in the database.

• Replaced hardcoded bacteremia and nares count queries with dynamic special collection counting
• Added descriptive strings for known special collection types
• Updated template to use a loop for displaying collection counts
