fix(settings): improve search functionality and UI integration

Fix search logic issues and enhance UI styling:
- Fix minimum query length validation (require 2+ characters)
- Add comprehensive debug logging for search operations
- Optimize search component styles for Obsidian integration
- Use Obsidian's native CSS variables for consistent styling
- Force override default input/button styles that conflict
- Improve keyboard navigation and accessibility
- Add responsive design and proper scrollbar styling
- Enhance search result display with proper spacing
- Add comprehensive test suite for search functionality

Technical improvements:
- Replace hardcoded values with Obsidian CSS variables
- Fix box-shadow and border conflicts with \!important flags
- Standardize icon sizes and button dimensions
- Improve focus states and interaction feedback
- Add proper z-index layering for popover elements
