refactor(ui): separate diff dots with distinct colors, align modal badges

Replace 2 combined dots with 4 individual dots per diff type:
- CUI/TVA (red), Denumire (orange), Adresa (blue), Pret (green)
- Remove redundant price column from dashboard table
- Add --compare design token (orange) for denomination mismatches
- Align modal badge colors with table dot colors (4 separate CSS classes)
