Feature: Add clear button and fix dropdown z-index

Changes:
1. Added clear (X) button in search bar
   - Only appears when there's text
   - Clears search query AND filters
   - Clean X icon with hover effect

2. Fixed dropdown z-index
   - Changed from z-index: 50 to z-index: 9999
   - Now appears above all other UI elements
