feat(theme): add 5 preset color themes (Nord/Gruvbox/Monokai/Dracula/Solarized) with popover selector

Implements Approach C (dual-attribute: data-theme + data-theme-preset),
keeping all 106 existing [data-theme="dark"] overrides unchanged.

- Colors: 5 professionally designed oklch palettes in tokens/colors.css
- UI: popover theme selector with mode (Light/Dark/Auto) + preset grid
- JS: cycleTheme(), setPreset(), localStorage persistence
- Locale: 12 new translation keys across 10 languages
- Polish: solid accent swatches matching flat token-driven aesthetic
