refactor: clean up ChatSearch component code

- Remove unused variables (currentSearchTerm)
- Simplify redundant logic and conditions
- Extract CSS constants to eliminate duplication
- Consolidate navigation functions (navigateToResult → navigateToIndex)
- Remove duplicate keyboard shortcuts (Cmd+Arrow keys)
- Streamline lifecycle methods and event handlers
- Clean up excessive comments while preserving functionality
- Maintain all existing features: Ctrl+F, real-time search, yellow highlighting,
  chronological ordering, Enter/Shift+Enter navigation, blue flash, fixed-width

Code is now clean, professional, and simple without duplication of effort.
