Replace hex color codes with friendly color names for customers

- Add colorNames utility with 80+ standard color names
- Map hex codes to human-readable names (Black, Navy, Red, Teal, etc)
- Display color names in product page (with hex tooltip for reference)
- Show selected color name below color swatches
- Update shopping cart to display color names instead of hex codes
- Admin color picker shows both name and hex code for clarity

Improves UX for customers who don't understand hex color codes.
Keeps hex codes for internal data and system tooltips.
