enhance: Implement dynamic message template system with progress tracking

- Add comprehensive message template system with 5 distinct message types
- Implement progress tracking for multi-strategy geocoding attempts
- Add dismissible messages with auto-timeout functionality
- Enhance visual design with proper spacing, shadows, and animations
- Add specialized geocoding success messages with location details
- Improve user experience with contextual progress indicators
- Support HTML content in messages for better formatting
