refactor: improve code quality and reduce duplication

- Create constants file for badge colors, labels, and storage keys
- Extract category filtering logic to reusable helper functions
- Create reusable Badge component (reduces ~80 lines of duplication)
- Migrate inline styles to Tailwind classes in SoftwareCard and ConfigOption
- Fix double toggle handlers (remove redundant onChange on checkboxes)
- Remove 6 duplicate section header comments in software-catalog.js

Code quality improvements:
- Reduced code duplication across components
- Centralized configuration values
- Improved maintainability with helper functions
- Cleaner component structure with Tailwind utilities

Bundle size: 393KB (121KB gzipped) - maintained 94% reduction
