Restructure assets to top-level package and add Reset Map button

- Move assets from internal/assets to top-level assets/ package for clean embed directive
- Consolidate all static files in single location (assets/static/)
- Remove duplicate static file locations to maintain single source of truth
- Add Reset Map button to map controls with full functionality
- Implement resetMap() method to return map to calculated origin position
- Store origin in this.mapOrigin for reset functionality
- Fix go:embed pattern to work without parent directory references
