[Added, Improved, Fixed] Branch filtering and faster home page

Added

Branch filtering

Recruiters can now view and filter jobs by branch across the home page, MetricsATS dashboard, and CSV exports.
The new branch column gives instant context, while the filter lets you focus on a specific location or division without leaving the page.

Improvements

• Home page loads up to seven times faster thanks to behind-the-scenes pagination and query optimizations
• The jobs list now paginates results and supports server-side filtering for smoother browsing on large accounts
• Analytics counts now include "Not Qualified" candidates so totals reflect every applicant stage

Fixes

• CSV exports now correctly respect the selected branch filter, ensuring downloaded data matches what you see on screen
